Executed Gunpowder Plotters

Capital punishment, also known as the death penalty, is the state-sanctioned practice of deliberately killing a person as a punishment for an actual or supposed crime, usually following an authorized, rule-governed process to conclude that the person is responsible for violating norms that warrant said punishment. The sentence ordering that an offender is to be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is ''condemned'' and is commonly referred to as being "on death row".

Crimes that are punishable by death are known as ''capital crimes'', ''capital offences'', or ''capital felonies'', and vary depending on the jurisdiction, but commonly include serious crimes against the person, such as murder, mass murder, aggravated cases of rape (often including child sexual abuse), terrorism, aircraft hijacking, war crimes, crimes against humanity, and genocide, along with crimes against the state such as attempting to overthrow government, treason, espionage, sedition, and piracy, among other crimes. Also, in some cases, acts of recidivism, aggravated robbery, and kidnapping, in addition to drug trafficking, drug dealing, and drug possession, are capital crimes or enhancements. However, states have also imposed punitive executions, for an expansive range of conduct, for political or religious beliefs and practices, for a status beyond one's control, or without employing any significant due process procedures. Judicial murder is the intentional and premeditated killing of an innocent person by means of capital punishment. For example, the executions following the show trials in Russia during the Great Purge of 1937–1938 were an instrument of political repression.

Etymologically, the term ''capital'' (lit. "of the head", derived via the Latin ' from ', "head") refers to execution by beheading, but executions are carried out by many methods, including hanging, shooting, lethal injection, stoning, electrocution, and gassing.

As of 2022, 55 countries retain capital punishment, 109 countries have completely abolished it ''de jure'' for all crimes, seven have abolished it for ordinary crimes (while maintaining it for special circumstances such as war crimes), and 24 are abolitionist in practice. Although the majority of nations have abolished capital punishment, over 60% of the world's population live in countries where the death penalty is retained, such as China, India, the United States, Singapore, Indonesia, Pakistan, Bangladesh, Nigeria, Egypt, Saudi Arabia, Iran, Japan, and Taiwan.

Capital punishment is controversial in several countries and states, and positions can vary within a single political ideology or cultural region. Amnesty International declares that the death penalty breaches human rights, stating "the right to life and the right to live free from torture or cruel, inhuman or degrading treatment or punishment." These rights are protected under the Universal Declaration of Human Rights, adopted by the United Nations in 1948. In the European Union (EU), Article 2 of the Charter of Fundamental Rights of the European Union prohibits the use of capital punishment. The Council of Europe, which has 46 member states, has sought to abolish the use of the death penalty by its members absolutely, through Protocol 13 of the European Convention on Human Rights. However, this only affects those member states which have signed and ratified it, and they do not include Armenia and Azerbaijan. The United Nations General Assembly has adopted, throughout the years from 2007 to 2020, eight non-binding resolutions calling for a global moratorium on executions, with a view to eventual abolition.

History

Execution of criminals and dissidents has been used by nearly all societies since the beginning of civilizations on Earth. Until the nineteenth century, without developed prison systems, there was frequently no workable alternative to ensure deterrence and incapacitation of criminals. In pre-modern times the executions themselves often involved torture with cruel and painful methods, such as the breaking wheel, keelhauling, sawing, hanging, drawing, and quartering, burning at the stake, flaying, slow slicing, boiling alive, impalement, mazzatello, blowing from a gun, schwedentrunk, and scaphism. Other methods which appear only in legend include the blood eagle and brazen bull.

The use of formal execution extends to the beginning of recorded history. Most historical records and various primitive tribal practices indicate that the death penalty was a part of their justice system. Communal punishments for wrongdoing generally included blood money compensation by the wrongdoer, corporal punishment, shunning, banishment and execution. In tribal societies, compensation and shunning were often considered enough as a form of justice. The response to crimes committed by neighbouring tribes, clans or communities included a formal apology, compensation, blood feuds, and tribal warfare.

A blood feud or vendetta occurs when arbitration between families or tribes fails or an arbitration system is non-existent. This form of justice was common before the emergence of an arbitration system based on state or organized religion. It may result from crime, land disputes or a code of honour. "Acts of retaliation underscore the ability of the social collective to defend itself and demonstrate to enemies (as well as potential allies) that injury to property, rights, or the person will not go unpunished."

In most countries that practise capital punishment, it is now reserved for murder, terrorism, war crimes, espionage, treason, or as part of military justice. In some countries sexual crimes, such as rape, fornication, adultery, incest, sodomy, and bestiality carry the death penalty, as do religious crimes such as Hudud, Zina, and Qisas crimes, such as apostasy (formal renunciation of the state religion), blasphemy, moharebeh, hirabah, Fasad, Mofsed-e-filarz and witchcraft. In many countries that use the death penalty, drug trafficking and often drug possession is also a capital offence. In China, human trafficking and serious cases of corruption and financial crimes are punished by the death penalty. In militaries around the world courts-martial have imposed death sentences for offences such as cowardice, desertion, insubordination, and mutiny.

Ancient history

Elaborations of tribal arbitration of feuds included peace settlements often done in a religious context and compensation system. Compensation was based on the principle of ''substitution'' which might include material (for example, cattle, slaves, land) compensation, exchange of brides or grooms, or payment of the blood debt. Settlement rules could allow for animal blood to replace human blood, or transfers of property or blood money or in some case an offer of a person for execution. The person offered for execution did not have to be an original perpetrator of the crime because the social system was based on tribes and clans, not individuals. Blood fe
