Hanging is the oldest but most widely used method of execution in the world today. In 2022, at least 630 men and 15 women were hanged in eleven countries: Bangladesh, Egypt, Iran, Iraq, Japan, Kuwait, Myanmar, Palestine, Singapore, South Sudan, and Syria.
Hanging remains the standard method of execution in many retentionist countries, notably Japan, Singapore, Malaysia, South Korea, India, Pakistan, Bangladesh, several African countries (including Botswana, Kenya, and Zimbabwe), several Middle Eastern countries (including Iran, Iraq, Egypt, Jordan, Kuwait, Lebanon, and Syria), and in most Caribbean states. It was also a lawful method, as an option to lethal injection, in the American state of Washington, which carried out two hangings after the re-introduction of the death penalty in 1976.
It was used extensively in Iraq under Saddam Hussein and continues to be the lawful method there under the new government, which carried out 43 executions during 2018 according to official figures. Iraq primarily uses short drop hanging.
Hanging originated as a method of execution in Persia (now Iran) about 2,500 years ago for male criminals only (women were strangled at the stake for the sake of decency). It was the method of choice in many countries because it produced a highly visible deterrent without the blood and gore of beheading. In early times, it was considered ideal because it was simple to carry out, did not give the condemned person a particularly cruel death by the standards of the day, made a good public spectacle because the prisoner was elevated above the crowd, and required equipment that was easily obtained—a tree, a length of rope, and a ladder or cart being widely available. Unlike beheading, it did not require a highly skilled executioner. Beheading was the other most common form of execution, adopted as the sole means by some countries.
There is no means of knowing how many people have been hanged worldwide over the last 2,000 years, but the total is likely at least half a million. Between 1800 and 1964, over 5,000 people were executed by hanging in Britain. In America, an estimated 9,300 people—including up to 356 women—were hanged from the early 1600s up to 1996. Hanging was the standard form of execution in many countries until the end of the 19th century, when a general trend emerged toward abolition or toward methods considered more humane than the short drop method used at the time. It was the standard method across Britain and its colonies, and was widely used in France prior to the French Revolution, as well as in Germany and pre-communist Russia. It remained the lawful method in all American states until 1890 and continued in some until the suspension of the death penalty in 1968. Hanging was also utilized by many other countries that have since abolished capital punishment, including Australia, Austria, Canada, Czechoslovakia, Hungary, Ireland, New Zealand, Poland, and South Africa. Adolf Hitler reintroduced it in Nazi Germany, where large numbers of prisoners were executed by this method in prisons, concentration camps, and field executions by German soldiers between 1937 and 1945.
Processes of Judicial Hanging
There are four primary forms of judicial hanging:
- Short Drop Hanging: The prisoner drops only a few inches. Body weight and physical struggling cause the noose to tighten, normally resulting in death by strangulation or by carotid/vagal reflex. Pole hanging is a notable variation of this method.
- Suspension Hanging: The condemned person is hoisted into the air using a crane, pulley, or other mechanical hoist. Death occurs through the same physiological mechanisms as in short drop hanging.
- Standard Drop Hanging: The prisoner drops a predetermined distance—typically between 4 and 6 feet—which may or may not fracture the cervical vertebrae. This was the conventional method adopted in the United States throughout the late 19th and early 20th centuries.
- Measured or “Long Drop” Hanging: Introduced universally in Britain from 1874 onward, this method calculates the exact distance of fall based on the prisoner’s weight, height, and build. It is engineered specifically to dislocate and break the neck instantly. This technique was subsequently adopted across British colonies and in various other countries seeking a faster, more humane procedure.
The Short Drop Method
Hanging with little or no free fall is still practiced in some Middle Eastern countries, notably Iran, and remains far more common globally in the 21st century than the long drop method.
Short drop hanging was effectively universal until around 1850 and was routinely carried out in public settings. The condemned could be suspended by several means: from the rear of a cart (or later a motorized vehicle), from horseback as occasionally seen in the United States, by withdrawing a ladder or standing platform (as utilized in Nazi executions and modern Iranian indoor prison executions), or via trapdoor mechanisms introduced in Britain in 1760 and later adopted elsewhere.
In 2020, Iranian prison physician Dr. Norouzpour described the medical realities of this process:
“One of the duties of a prison doctor is to check the consciousness of the convict. No one will be given sedatives or any other medicine before execution.”
According to Dr. Norouzpour:
“Hanging causes instant death in 70% of cases, death in 30% of cases is due to obstruction of the airways and arteries, and in these cases it takes two to three minutes for death to occur. However the person being hanged does not remain conscious for more than 20 to 30 seconds.”
The Iranian Rules of Execution of Sentences mandate that the body remain suspended for 20 to 45 minutes. Following this period, the body is lowered, the attending physician formally certifies death, and the remains are transferred to the morgue for release to the family. These observations are corroborated by recorded footage of executions and historical newspaper accounts of 19th-century public hangings in Great Britain.
Suspension Hanging
Suspension hanging is currently utilized in Iran for public executions and was previously employed in Afghanistan under Taliban rule, where condemned individuals were hoisted from crane jibs or tank gun barrels. In modern Iranian public executions, mobile cranes and recovery vehicle jibs equipped with hydraulic lifting arms serve as both the gallows structure and the lifting mechanism.
In 19th- and early 20th-century America, certain jurisdictions used an inverted mechanical arrangement. Instead of dropping the prisoner through a trapdoor, heavy counterweights attached to the rope via overhead pulleys were released by the executioner, jerking the condemned rapidly into the air:
- William E. Udderzook (1874): Executed in West Chester, Pennsylvania, using a counterweighted upward hoist.
- Charles Thiede (1896): Hanged in Utah using a similar weight-assisted drop-and-hoist setup.
- Gerald Chapman (1926): Executed in Connecticut on April 26, 1926. A weight running over a pulley was triggered by the warden via a foot lever, hoisting Chapman 12 feet into the air with enough force to fracture his cervical spine.
- Roxalana Druse (1887): Hanged in New York State using an upward-jerk gallows; the botched and traumatic nature of the execution contributed directly to New York’s transition to the electric chair, enacted at the end of the decade.
Standard Drop Hanging
Standard drop hanging employed an unadjusted drop distance of four to six feet throughout the late 19th and early 20th centuries in the United States. Rather than being calibrated to individual body mass, the drop length was often roughly equivalent to the prisoner’s height. While considered an improvement over the static short drop, this distance frequently failed to generate the kinetic energy needed to dislocate the cervical vertebrae. As a result, many prisoners died of slow strangulation, though impact from the heavy knot against the side of the neck often produced blunt-force unconsciousness.
Conversely, excessive drops occasionally caused traumatic decapitation, as occurred during the execution of Eva Dugan in Arizona in 1928. Standard drops were also used for the eleven senior Nazi officials executed after the Nuremberg trials, where several reportedly died slowly. The four Lincoln conspirators executed in 1865 received five-foot drops, with at least two struggling noticeably following suspension. Historical film records of American military executions of German war criminals at Landsberg and Bruchsal show nooses placed so the loop rested directly on the trapdoors, providing a drop approximately equal to the prisoner’s height; in those cases, the footage rarely reveals violent rope vibration or prolonged struggling.
The Measured or “Long Drop” Method
In 1872, English executioner William Marwood introduced the mathematically calculated drop for the execution of Frederick Horry at Lincoln Prison, establishing a standardized method designed to produce instantaneous unconsciousness. The physiological concepts had been researched and developed by Irish physicians as early as the mid-1850s, though countries such as Austria, Czechoslovakia, Poland, and Russia continued using short drops or pole methods.
The long drop relies on gravitational acceleration checked abruptly at the end of the rope. When the eyelet or knot is positioned submentally (beneath the left angle of the jaw), the sudden deceleration violently hyperextends and rotates the head backward and laterally. This combined momentum dislocates the upper cervical vertebrae and ruptures the spinal cord, inducing immediate deep coma. The later integration of a low-friction brass eyelet into the rope eye ensured smoother travel and more reliable cervical disruption.
The physical forces act primarily during the final 6 inches of the fall, completing the mechanical damage to the vertebrae in 0.02 to 0.03 seconds. During this impact, the noose diameter typically constricts by 5 to 7 inches.
Drop Calculations and Kinetic Standards
Between 1886 and 1892, following recommendations from the Aberdare Committee, British drop distances were calculated to yield a striking force of approximately 1,260 foot-pounds, targeting dislocation between C2–C3 or C3–C4:
$$\text{Drop (feet)} = \frac{1,260\text{ ft-lbs}}{\text{Body Weight (lbs)}}$$
Between 1892 and 1913, the target energy was reduced to 840 foot-pounds to prevent decapitation, although historical records indicate executioners frequently applied longer drops than the table specified. After 1913, official guidelines were revised to target approximately 1,000 foot-pounds, with drops strictly capped between 5 feet and 8 feet 6 inches. From roughly 1939 onward, British executioners commonly added 9 inches to the 1913 table values to produce a striking force near 1,100 foot-pounds.
This table remains the basis for modern executions in Singapore and Malaysia, and historically influenced practices in Australia, Canada, Egypt, and across the Caribbean. Pakistan, India, and Bangladesh utilize measured long drops derived from these principles.
British Drop Tables (1892 vs. 1913)
The condemned prisoner was weighed fully clothed on the day preceding the execution to calculate the required fall:

Note: The United States Military Execution Manual specifies drop dimensions broadly comparable to the 1913 table.
Physiological Causes of Death in Short Drop and Suspension Hanging
Short drop and suspension hanging account for the vast majority of judicial executions and suicidal hanging deaths worldwide.
Vascular Occlusion and Reflex Mechanisms
In executions using little or no drop, death results from a combination of airway occlusion, venous and arterial compression, and vagal reflex:
- Jugular Vein Occlusion: Requires approximately 4.5 pounds per square inch (psi) of pressure.
- Carotid Artery Compression: Requires approximately 11 psi of pressure, cutting off primary cerebral oxygenation and frequently provoking cardiac arrest via carotid sinus reflex stimulation.
- Tracheal Compression: Requires approximately 33 psi of direct pressure to close the airway.
- Vertebral Artery Compression: These vessels exit the protection of the cervical vertebrae near C4, requiring 40 to 50 psi to fully occlude.
Unconsciousness typically occurs within 8 to 15 seconds, though it can take up to a minute if arterial flow is incompletely blocked. Somatic brain death occurs within approximately 6 minutes, followed by cardiac standstill within 10 to 15 minutes.
Physical Manifestations
When jugular veins are occluded before carotid arteries, blood enters the cranium but cannot drain, causing the face to become engorged, cyanotic, and marked with petechial hemorrhages (ruptured capillaries in the skin and eyes). The base of the tongue is forced upward against the soft palate, causing the tongue to protrude. Conversely, when rapid vagal arrest occurs, the face often remains pale without marked petechiae. In both instances, an inverted “V” ligature furrow is left on the neck, with the apex at the knot.
Post-Suspension Reflexes and Motor Activity
Suspension is typically followed by an initial period of struggling (1 to 3 minutes), a brief quiescent interval, and a convulsive reflex phase:
- Involuntary limb contractions, spinal arching, and chest heaving are autonomic reactions triggered by hypoxia and hypercapnia (carbon dioxide accumulation), rather than conscious distress.
- Photographic reviews of 46 public short drop hangings in Iran revealed visible struggling in 10 cases, slight tongue protrusion in 4 cases, facial engorgement in 0 cases, drooling in 2 cases, and seminal emission/priapism in 2 cases.
- Clinical analyses of asphyxiation by the Working Group on Human Asphyxia document loss of consciousness at $10 \pm 3$ seconds, convulsive spasms lasting $14 \pm 3$ seconds, decerebrate rigidity (caused by brainstem ischemia) lasting $18 \pm 2$ seconds, and complete loss of muscle tone at $1\text{ minute } 31\text{ seconds } \pm 9\text{ seconds}$.
Regional Variants: Pole Hanging
Austria, Czechoslovakia, and Hungary developed a specialized form of short drop execution known as pole hanging. Rather than using an overhead scaffold beam, the condemned was positioned against a vertical timber post with a noose affixed to a ring or pulley at the top, while assistants applied downward force on an ankle rope running through a lower pulley.
Austria
In the late 19th century, Austrian executioner Josef Lang maintained that pole hanging was more humane than standard American drop hanging, asserting that unconsciousness arrived in less than one minute. Following World War II, British executioner Albert Pierrepoint carried out eight hangings at Graz-Karlau using the British long drop, after which Austrian authorities briefly reverted to pole hanging until its final execution on March 24, 1950 (Johann Trnka).
Czechoslovakia
Czechoslovak gallows consisted of a heavy wooden post approximately 3 meters high and 30 to 40 cm wide, equipped with an eyebolt, hook, or pulley at the summit. The executioner stood on an elevated platform behind the pole. The pinioned prisoner was positioned back-to-post, lifted via an armpit sling to allow placement of the thin cord noose, and then pulled sharply downward by assistants pulling the ankle line. The rapid tension on the thin cord induced prompt vagal and carotid reflex unconsciousness.
The method was documented on film during the May 22, 1946 execution of war criminal Karl Hermann Frank at Pankrác Prison, and was later used for political prisoner Milada Horáková in June 1950. In 1954, Czechoslovakia discontinued vertical post hanging, converting execution facilities in Prague and Bratislava to shallow-pit short drops operated by trapdoor levers inside the wall.
Hungary
Hungary retained pole hanging until its final execution on July 14, 1988 (Ernő Vadász). The Hungarian apparatus was slightly shorter (around 2.5 meters tall) and narrower (0.2 meters). Condemned individuals climbed a small stepped stool; the executioner adjusted the noose, the stool was removed, and assistant executioners pulled downward on ankle cords looped through a lower base bolt. The drop distance was minimal (0.15 to 0.2 meters), and prisoners were traditionally left unhooded until after death was certified.
Complications of Standard Drop Hangings
When an unmeasured standard drop fails to break the cervical vertebrae, the kinetic force causes severe soft-tissue trauma to the neck muscles, trachea, and skin without inducing immediate unconsciousness.
Former San Quentin Warden Clinton Duffy documented this outcome during the May 9, 1942 execution of Major Raymond Lisemba in California:
“The man hit bottom and I observed that he was fighting by pulling on the straps, wheezing, whistling, trying to get air, that blood was oozing through the black cap. I observed also that he urinated, defecated, and droppings fell on the floor, and the stench was terrible… I also saw witnesses pass out and have to be carried from the witness room. Some of them threw up.”
Lisemba’s heart continued beating for ten minutes. Upon post-mortem examination, extensive skin lacerations were found along the jawline, the facial tissues were intensely cyanotic, and the tongue was severely swollen and protruded.
Biomechanics and Post-Mortem Findings in Measured Drop Executions
In properly calculated long drop executions, the body accelerates for 0.5 to 0.75 seconds before hitting the end of the rope. The arresting kinetic energy (averaging 1,100 foot-pounds in post-1939 British practice) violently jerks the head backward and toward the side opposite the noose eyelet.
This rapid hyperextension produces bilateral pedicle fractures of the axis vertebra (C2) or fractures between C2 and C3, severing the high cervical spinal cord. Disruption above C4 severs the phrenic nerve controlling the diaphragm, instantly extinguishing spontaneous respiration while abolishing central nervous system activity.
Autopsy Protocol: Ruth Ellis (Executed July 13, 1955)
The post-mortem examination of Ruth Ellis—the last woman executed in the United Kingdom—was performed at HM Prison Holloway by forensic pathologist Dr. Keith Simpson:
- Subject: Ruth Ellis, age 28. Height: 5 ft. 2 in. Weight: 103 lbs.
- External Examination: Well-nourished subject. Deep ligature mark around the neck with the point of suspension situated 1 inch anterior to the angle of the left lower jaw. Vital reaction present in the underlying subcutaneous tissues. No facial ecchymoses or petechial hemorrhages. No evidence of physical struggle.
- Central Nervous System: Complete fracture-dislocation of the cervical spine at C2 with a 2-inch separation of the vertebral column; complete transverse transection of the spinal cord at that level.
- Respiratory Tract: Fractures of both wings of the hyoid bone, right wing of the thyroid cartilage, and larynx. Air passages clear; lungs entirely free of asphyxial congestion or petechiae.
- Cardiovascular & Abdominal: Heart, pericardium, and major vessels intact with no organic or petechial changes. Stomach contained minor food residue with an odor of brandy.
- Certified Cause of Death: Injuries to the central nervous system consequent upon judicial hanging.
Post-Mortem Cardiac Activity
Although cervical transection abolishes brainstem activity and consciousness within fractions of a second, autonomous cardiac action regularly persists. The heart’s intrinsic sinoatrial node continues generating electrical impulses independently of spinal control:
- Dr. Llewellyn A. Morgan (Newgate, 1887): Sphygmograph recordings of pulses from three hanged prisoners confirmed continued arterial pulsation for several minutes despite verified cervical dislocations.
- Hameln Prison Executions (1945–1946): British Army of the Rhine pathologist F. E. Buckland recorded audible heartbeats continuing for up to 25 minutes after execution in Nazi war criminals. To expedite multiple executions without leaving prisoners suspended for an hour, medical officers experimentally injected 10 cc of chloroform intracardially or intravenously 30 seconds after the drop, stopping the heart within seconds.
- Subsequent Hameln Observations (1946): During eight executions conducted by Albert Pierrepoint on March 8, 1946, without chloroform, stethoscopic examinations verified heart action ceasing between 10 and 15 minutes post-drop. Electrocardiographic tracings taken during subsequent executions on May 15, 1946, recorded electrical nodal complexes for up to 25 minutes.
Execution Hardware and Ancillary Equipment
Gallows Architecture
Scaffolding engineering evolved significantly over two centuries:
- The New Drop (1760–1783): First used at Tyburn for the Earl Ferrers (1760) and later established at Newgate Prison (1783), replacing carts with a collapsing floor platform.
- British Enclosed Chambers: Late 19th- and 20th-century British gallows moved entirely indoors, eliminating overhead upright timbers in favor of concealed structural steel beams set into the masonry walls or ceiling above a double-leaf trapdoor operated by an iron floor lever.
- North American Gallows: Traditionally utilized outdoor elevated wooden platforms with a single-leaf trap. The modern gallows formerly maintained at Washington State Penitentiary in Walla Walla featured overhead eyebolts mounted above an electro-mechanically released trapdoor.
Ligature Construction
- British/Commonwealth Standard: Constructed from 13 feet of 3/4-inch diameter prestretched hemp rope fitted with a countersunk brass eyelet and a vulcanized rubber or leather positioning washer. The portion bearing against the neck was encased in soft sheepskin or morocco leather to prevent rope friction and skin tearing.
- American Standard: Fabricated in accordance with military manuals from 30 feet of 3/4-inch to 1-inch manila hemp rope, pre-stretched, boiled, and treated with wax or tallow to minimize coiling. It features a sliding hangman’s knot of 5 to 13 coils positioned sub-aurally below the left ear.
- Modern Synthetics: Braided nylon lines are frequently used in modern Iranian crane suspensions due to tensile strength, although their elasticity makes them unsuitable for measured long drop execution tables.
Pinioning and Hooding
- Restraints: Prisoners are routinely secured using heavy leather pinioning belts or handcuffs behind the back. Ankle straps are applied on the scaffold trapdoors to hold the feet together and prevent the prisoner from straddling the trap opening. In Britain, knee and thigh straps were historically added for female prisoners to prevent skirts from billowing during the drop.
- Hoods: A black cotton or white linen hood is placed over the prisoner’s head immediately prior to the noose being adjusted. Hooding serves three practical functions: it prevents the condemned from flinching or altering head position during the lever pull, shields witnesses and officials from facial distortion, and reduces skin abrasion from the ligature.
Contemporary Executions
Kuwait: Nayef Palace (May 31, 2004)
Three men convicted of murder—Marzook Al-Saeed, Saeed Al-Saeed, and Hamad Al-Dihani—were executed simultaneously on an elevated outdoor scaffold at Nayef Palace in Kuwait City. The men were restrained in leather wrist-and-arm harnesses, positioned over individual double-leaf trapdoors, and fitted with British-style leather-lined eyelet nooses, rubber stop washers, and black hoods.
Each was given a measured drop of approximately 7 feet. Auditory heartbeat monitoring with stethoscopes confirmed cardiac cessation at 5 minutes 20 seconds, 6 minutes, and 8 minutes respectively, with no signs of post-drop struggling.
Iraq: Execution of Saddam Hussein (December 30, 2006)
Former Iraqi president Saddam Hussein was executed at 6:10 AM on December 30, 2006, in the Khadamiya district of northern Baghdad. He was positioned over a steel tread-plate trapdoor, declining the traditional black hood.
A dark neck scarf was placed beneath an American-pattern 7-coil noose with the knot aligned under his left ear. Upon release of the trap, he fell a distance slightly greater than his height; forensic analysis of photographic and video records confirmed instant cervical dislocation and immediate death without post-suspension struggling. The body was lowered after hanging for ten minutes.
Iran: Public Crane Execution (July 15, 2007)
A 29-year-old woman identified as Houriyeh and two male co-defendants were executed publicly via crane suspension. The three were restrained with hand cuffs and leg shackles; American-style coiled nooses were attached to a central spreader bar suspended from a mobile hydraulic crane.
Upon being lifted off the ground, the two male prisoners became limp almost immediately, while the female prisoner exhibited severe physical struggling and convulsive contractions for roughly 60 seconds before movement ceased.
Neurophysiology of Pain and Consciousness
Measured Drop (Spinal Transection)
During a correctly executed measured drop, the interval between trapdoor release and impact arrest ranges from 0.5 to 0.75 seconds. The striking force breaks the neck in 0.02 to 0.03 seconds. Neurophysiological data submitted to historical commissions, including the Aberdare Committee, indicates that complete transection of the high spinal cord causes a total collapse of afferent sensory signaling to the brainstem within 0.3 seconds.
The abrupt severance triggers massive stochastic depolarization throughout severed axonal pathways, destroying signal coherence and inducing immediate, irreversible unconsciousness. Any potential sensation of pain is limited to the initial mechanical impact (< 0.05 seconds).
Short Drop and Suspension (Asphyxia and Ischemia)
In short drop or suspension hangings where the spinal column remains intact, the experience is marked by acute conscious distress:
- Respiratory Obstruction: Condemned individuals experience violent respiratory hunger against an obstructed airway, compounded by intense compression of the tongue and laryngeal cartilage.
- Ischemic Sensation: Survivors of incomplete suicidal and accidental hangings describe extreme cranial bursting sensations, visual flashes (“greying or blacking out”), and severe motor paresis before losing consciousness.
- Survivor Testimony: In February 1996, an Iranian prisoner named Niazali survived a short drop hanging when he was pardoned by the victim’s family after several minutes on the rope. In an interview with the Kayhan newspaper, he described the sensation:
“That first second lasted like a thousand years. I felt my arms and legs jerking out of control. Up on the gallows in the dark, I was trying to fill my lungs with air, but they were crumpled up like plastic bags.”
Comparative Analysis: Measured Drop Hanging vs. Lethal Injection
| Clinical & Operational Feature | Measured Long Drop Hanging | Three-Drug Lethal Injection |
| Total Procedure Duration | 15 to 30 seconds from cell departure to drop | 15 to 45 minutes from gurney transfer to death |
| Duration of Conscious Exposure | Typically under 20 seconds | 10 to 30 minutes during line insertion and saline flush |
| Time to Unconsciousness | Immediate (< 0.05 seconds upon rope arrest) | 15 to 60 seconds after anesthetic injection |
| Time to Complete Asystole | 8 to 20 minutes (autonomous pacemaker activity) | 5 to 15 minutes after potassium chloride infusion |
| Primary Failure Modes | Decapitation (excess drop) or strangulation (short drop) | Peripheral vein collapse, infiltration, or awareness during paralysis |
| Witness Impact | Sudden, violent mechanical deceleration | Medicalized clinical setting, though prone to prolonged access delays |
The Post-Mortem Report
In some parts of Britain, such as the three London “hanging” prisons, an autopsy was routinely carried out during the 20th century on an executed person’s body to establish the exact cause of death. One detailed surviving record is the autopsy report of Ruth Ellis, performed by forensic pathologist Professor Keith Simpson at HM Prison Holloway on July 13, 1955.

Physiological and Post-Mortem Phenomena
Following judicial hanging by any method, specific external and internal physical manifestations typically appear:
- Cutaneous Markings: Bruising and deep ligature furrows remain along the neck tissue where the noose constricted.
- Sphincter Relaxation: Effusions of urine and feces frequently occur as oxygen deprivation causes total relaxation of sphincter muscle tone, or as an involuntary response to an extreme adrenaline rush prior to suspension.
- Somatic Death Timeline: Total cellular death typically occurs within 30 minutes once tissues are fully starved of oxygen. This biological window was the primary operational reason British execution protocols mandated leaving the body suspended for a full hour before taking it down.
- Post-Mortem Priapism and Ejaculation: Male prisoners occasionally exhibit penile engorgement (priapism) due to gravitational pooling of blood into the lower limbs and pelvic floor after cardiac arrest. Seminal effusion on the rope is also documented. In 1853, Dr. Charles Croker King examined the body of John Hurley immediately after his hanging in Galway, confirming spermatozoa under a microscope; such reactions are caused by pelvic nerve stimulation, carotid/vagal nerve pressure, and cerebral hypoxia during the spinal shock phase.
Execution Equipment and Infrastructure
The Gallows Scaffolding
Scaffold construction transitioned significantly from makeshift field posts to specialized indoor execution chambers:
- The New Drop (1760–1783): First used in Britain for the execution of Earl Ferrers in 1760, this design utilized a small collapsible box platform rising 12 inches above the scaffold floor. It was adopted at London’s Newgate Prison in 1783, formalizing the trapdoor method.
- Indoor British Chambers: By the 20th century, British scaffolds moved entirely indoors. Upright timber posts were removed in favor of concealed structural steel beams set into the masonry or ceiling directly over a two-leaf trapdoor operated by an iron floor lever.
- North American Variants: American designs traditionally featured elevated outdoor wooden platforms with a single-leaf trap. Modern installations, such as the former gallows at Washington State Penitentiary in Walla Walla, used heavy iron eyebolts mounted over an electro-mechanically released single-leaf trapdoor.
Ligature Design and Mechanics
- British and Commonwealth Pattern: Utilized a 13-foot length of 3/4-inch diameter prestretched hemp rope. English executioner William Marwood introduced a countersunk brass eyelet (thimble) held by a leather or rubber stop washer, allowing the rope to run smoothly without lubrication. The contact area was encased in soft sheepskin or morocco leather to prevent severe rope burn.
- American Coiled Noose: Fabricated in accordance with military manuals from 30 feet of 3/4-inch to 1-inch manila hemp rope, boiled to remove elasticity and treated with tallow, wax, or soap. It featured a sliding hangman’s knot of 5 to 13 coils positioned sub-aurally below the left ear to deliver a blunt-force blow to the side of the neck.
- Synthetic Rope: Modern Iranian short drop and suspension hangings commonly employ woven nylon cordage. While highly resistant to breakage, its elasticity makes it unsuitable for calculated long drop tables.
Hooding and Pinioning Protocols
- The Hood: A white linen hood (traditional in Britain, Australia, and South Africa) or a black cotton/denim hood (standard in the United States and the Middle East) is placed over the prisoner’s head immediately prior to positioning the noose. Hooding prevents the prisoner from shifting head position as the lever is thrown, reduces ligature abrasions, and shields witnesses from facial trauma.
- Pinioning: Hands are secured behind the back using leather pinioning straps or handcuffs. Ankle straps are applied once the prisoner stands over the drop to hold the feet together and prevent them from catching their boots on the edges of the opening trapdoors. In Britain, thigh straps were also used for female prisoners to prevent skirts from billowing during the drop.
- Auxiliary Restraints: Special boards or chairs have been used when a prisoner could not stand. Charles Campbell was strapped to a collapse board prior to his 1994 execution in Washington State, falling through the trap while secured to the board.
Contemporary Executions
Nayef Palace, Kuwait (May 31, 2004)
Three men convicted of murder—Marzook Al-Saeed, Saeed Al-Saeed, and Hamad Al-Dihani—were executed simultaneously on an elevated outdoor scaffold at Nayef Palace in Kuwait City:
- Restraint and Rigging: The men were secured with leather wrist harnesses, placed over individual double-leaf trapdoors, and fitted with British-style leather-lined eyelet nooses, rubber stop washers, and black hoods.
- Outcome: Each received a measured long drop of approximately 7 feet. Stethoscopic monitoring confirmed cardiac cessation at 5 minutes 20 seconds, 6 minutes, and 8 minutes respectively, with no signs of post-drop struggling.
Saddam Hussein, Iraq (December 30, 2006)
Former Iraqi president Saddam Hussein was executed at 6:10 AM on December 30, 2006, in the Khadamiya district of northern Baghdad:
- Procedure: Positioned over a steel tread-plate trapdoor, he refused the black hood. A dark neck scarf was placed beneath an American-pattern 7-coil noose with the knot aligned under his left ear.
- Outcome: The trap released and he dropped slightly more than his own height. Photographic and video evidence verified instantaneous cervical fracture and absence of movement; he was cut down after hanging for ten minutes.
Public Crane Execution, Iran (July 15, 2007)
A 29-year-old woman identified as Houriyeh and two male co-defendants were executed publicly in Iran using crane suspension:
- Procedure: The three prisoners stood shackled and handcuffed while American-style coiled nooses attached to a spreader bar were fitted around their necks.
- Outcome: The crane jib hoisted all three simultaneously. While both male prisoners became limp almost immediately, the female prisoner exhibited severe physical struggling and convulsive contractions for roughly 60 seconds before movement ceased.
Neurophysiology of Pain and Consciousness
Measured Drop (High Cervical Transection)
During a correctly executed measured drop, the entire mechanical phase takes between 0.5 and 0.75 seconds from trapdoor opening to rope arrest. The cervical vertebrae separate within 0.02 to 0.03 seconds of deceleration.
Scientific evidence presented to commissions such as the Aberdare Committee indicates that complete severance of the high spinal cord produces an immediate disruption of afferent neural signals to the brainstem within 0.3 seconds. Massive depolarization across the severed nerve ends causes signals to become entirely stochastic (randomized), extinguishing conscious awareness. Any sensation of pain is limited to the impact interval, lasting no more than fractions of a second.
Short Drop and Suspension (Asphyxia and Ischemia)
Without an adequate fall to fracture the spinal column, death occurs through vascular occlusion and respiratory obstruction, resulting in marked conscious distress:
- Respiratory Distress: The condemned experiences intense air hunger against an occluded trachea, with the base of the tongue compressed against the palate.
- Vascular Sensations: Survivors of non-fatal hangings report acute bursting sensations in the cranial cavity, flashes of light, and severe motor paresis before losing consciousness.
- Survivor Account: In February 1996, an Iranian prisoner named Niazali survived a short drop hanging after being pardoned by the victim’s family while on the rope. In an interview with the Kayhan newspaper, he described the physical sensation:
“That first second lasted like a thousand years. I felt my arms and legs jerking out of control. Up on the gallows in the dark, I was trying to fill my lungs with air, but they were crumpled up like plastic bags.”
Comparative Analysis: Measured Drop Hanging vs. Lethal Injection
| Clinical and Operational Parameter | Measured Long Drop Hanging | Three-Drug Lethal Injection |
| Total Procedure Duration | 15 to 30 seconds from cell departure to drop | 15 to 45 minutes from gurney transfer to death |
| Duration of Conscious Exposure | Typically under 20 seconds | 10 to 30 minutes during catheter insertion and vein checks |
| Time to Unconsciousness | Immediate (< 0.05 seconds upon rope arrest) | 15 to 60 seconds after anesthetic injection |
| Time to Complete Asystole | 8 to 20 minutes (autonomous nodal action) | 5 to 15 minutes after potassium chloride infusion |
| Primary Failure Modes | Decapitation (excess drop) or strangulation (short drop) | Peripheral vein collapse, line infiltration, awareness during paralysis |
| Witness Impact | Sudden, violent mechanical impact | Medicalized setting, though prone to prolonged access delays |
Conclusions
When carried out with an accurately measured drop and modern low-friction hardware, hanging produces rapid cervical dislocation, severing the spinal cord and rendering the condemned instantly unconscious. In mid-20th-century British practice, this standardized sequence was designed to minimize physical and mental suffering.
Conversely, hanging methods that omit a calculated drop—such as short drop, upward-jerk, or simple suspension—rely on gradual strangulation and carotid occlusion. These unmeasured techniques frequently prolong consciousness, resulting in extensive motor struggling and severe physical distress before somatic death occurs.
