The Iron Collar of Death: Why Did the Garrote Execution Method Use a Metal Neck Restraint?

Throughout human history, few execution methods have been as brutal as the garrote – a strangulation device using a rope or metal collar, widely used in Spain and its former colonies for centuries. Unlike hanging, which is designed to break the victim’s neck, the garrote was engineered to cause a slow, painful death by gradually compressing the trachea and carotid arteries. But the most distinctive feature of this method was the iron collar – a heavy metal device bolted to the execution chair, wrapped around the victim’s neck, and tightened using a lever or screw. Why was this brutal metal tool used, and why did it cause such horror? This article decodes the history and mechanism of the “collar of death.”
1. The Origin of the Garrote: From Torture Device to Official Execution Method
The garrote originated in medieval Spain, initially used as a torture instrument before becoming an official execution method. The name “garrote” comes from the Old Spanish word “garrote” (meaning “stick” or “rope”), referring to the wooden or metal rod turned to tighten the rope around the victim’s neck.
By the 18th and 19th centuries, the garrote had become Spain’s standard execution method for common criminals, particularly those sentenced to death for murder or treason. The method was later introduced to Spain’s colonies in Latin America, where it remained in use well into the 20th century.
2. The Anatomy of the “Collar of Death”: Iron Ring and Strangulation Mechanism
The iron collar was not a simple device. It was a complex system of components designed to maximize the efficiency (and brutality) of death.
Main components of the garrote:

When the executioner turned the lever or screw, the iron collar gradually tightened around the victim’s neck. The constriction not only blocked the trachea (causing suffocation) but also compressed the carotid arteries (supplying blood to the brain), leading to unconsciousness within seconds and death within minutes. However, unlike hanging – which typically causes rapid neck fracture and immediate death (if performed correctly) – the garrote was designed to prolong death, creating a prolonged and agonizing final struggle.
3. Why Was an Iron Collar Used? Three Main Reasons
The use of a metal collar instead of a simple rope was not accidental. It served three strategic purposes:
A. Immobilization of the Victim – Preventing Resistance
A dying person has a natural instinct to struggle and try to escape their restraints. The iron collar, securely bolted to the chair, made it nearly impossible for the victim to move their head or neck. This ensured that the strangulation process proceeded smoothly, uninterrupted by sudden convulsions. In other words, the iron collar turned the victim into an immobile target, completely at the mercy of the death machine.
B. Ensuring Even and Precise Constriction Pressure

Unlike rope, which can stretch or slip under pressure, the iron collar was rigid and non-elastic. When the lever was turned, the constricting force was transmitted directly and evenly around the entire circumference of the neck. This ensured that the trachea and carotid arteries were fully compressed, causing death more quickly (compared to other crude strangulation methods) and – crucially – irreversibly.
C. Psychological Terror – A Deterrent Tool
The cold sensation of metal against flesh, the creaking sound of the screw tightening millimeter by millimeter – all of this created a horrifying psychological experience not only for the victim but also for the witnesses. The iron collar was a tangible symbol of state brutality. It was designed not just to kill, but to terrify others into submission.
4. Variations of the Garrote: From Crude to “Modern”
The garrote evolved over time:
Crude garrote (medieval): A wooden or metal rod attached to a rope looped around the victim’s neck. Turning the rod tightened the rope.
Chair garrote (18th-19th century): The victim was strapped to a wooden chair, with an iron collar fixed in place. A large screw at the back of the chair was turned to tighten the collar.
“Modern” garrote (20th century): Some later versions used a pointed spike (punal) attached to the collar, which pierced the victim’s spinal cord as the screw was tightened, ensuring faster death – though no less brutal.
5. Where and When Was the Garrote Used?

The garrote was the standard execution method in:
Spain: From the 18th century until the abolition of the death penalty in 1995.
Former Spanish colonies: Particularly in Latin America, including Cuba, Mexico, Puerto Rico, and the Philippines (until the early 20th century).
Andorra: Where the garrote was used until 1990.
The most famous execution by garrote was that of Salvador Puig Antich, a Spanish anti-Franco activist executed in 1974 – he was the last person executed by this method in Spain.
6. Why Was the Garrote So Horrifying? The Psychology of a Slow Death
The horror of the garrote came not only from the painful death but also from its public and ritualistic nature.
Garrote executions were often public spectacles, drawing large crowds. The victim was strapped to the chair, the iron collar locked in place. The executioner slowly turned the lever, and the crowd could watch the victim’s face contort, their tongue protrude, their eyes bulge – a gruesome spectacle designed to shock and deter.
For the victim, the final moments were a nightmare: the cold sensation of metal, the creaking sound of the screw, and the awareness that each millimeter the collar tightened brought them closer to death. Unlike the guillotine or hanging (which could cause rapid death), the garrote prolonged suffering and fear for minutes.
7. Conclusion: The Legacy of the Iron Collar

The garrote was not just an execution method; it was a symbol of the absolute power of the state over the life and death of its citizens. The iron collar – cold, unfeeling, inescapable – embodied systematic brutality. It was designed to kill slowly, kill painfully, and kill in public view.
Today, the garrote is no longer used. The death penalty has been abolished in most countries that once employed it. But the wooden chairs and iron collars – now displayed in museums – remain a haunting reminder of what humans can do to their fellow humans in the name of justice.
