An outlaw is a person declared as outside the protection of the law. In pre-modern societies, all legal protection was withdrawn from the criminal, so that anyone was legally empowered to persecute or kill them. Outlawry was thus one of the harshest penalties in the legal system. In early Germanic law, the death penalty is conspicuously absent, and outlawing is the most extreme punishment, presumably amounting to a death sentence in practice. The concept is known from Roman law, as the status of homo sacer, and persisted throughout the Middle Ages.
In the common law of England, a "writ of outlawry" made the pronouncement Caput lupinum ("Let his be a wolf's head"), equating that person with a wolf in the eyes of the law. Not only was the subject deprived of all legal rights, being outside the "law", but others could kill him on sight as if he were a wolf or other wild animal. Women were declared "waived" rather than outlawed but it was effectively the same punishment.

Among other forms of exile, Roman law included the penalty of interdicere aquae et ignis ("to forbid water and fire"). People so penalized were required to leave Roman territory and forfeit their property. If they returned, they were effectively outlaws; providing them the use of fire or water was illegal, and they could be killed at will without legal penalty.
Interdicere aquae et ignis was traditionally imposed by the tribune of the plebs, and is attested to have been in use during the First Punic War of the third century BC by Cato the Elder. It was later also applied by many other officials, such as the Senate, magistrates, and Julius Caesar as a general and provincial governor during the Gallic Wars. It fell out of use during the early Empire.

In English common law, an outlaw was a person who had defied the laws of the realm, by such acts as ignoring a summons to court, or fleeing instead of appearing to plead when charged with a crime. The earliest reference to outlawry in English legal texts appears in the 8th century.
The term outlawry referred to the formal procedure of declaring someone an outlaw, i.e. putting him outside the sphere of legal protection. In the common law of England, a judgment of (criminal) outlawry was one of the harshest penalties in the legal system, since the outlaw could not use the legal system for protection, e.g. from mob justice. To be declared an outlaw was to suffer a form of civil or social death. The outlaw was debarred from all civilized society. No one was allowed to give him food, shelter, or any other sort of support—to do so was to commit the crime of aiding and abetting, and to be in danger of the ban oneself. A more recent concept of "wanted dead or alive" is similar, but implies that a trial is desired (namely if the wanted person is returned alive), whereas outlawry precludes a trial.
An outlaw might be killed with impunity, and it was not only lawful but meritorious to kill a thief fleeing from justice—to do so was not murder. A man who slew a thief was expected to declare the fact without delay, otherwise the dead man's kindred might clear his name by their oath and require the slayer to pay weregild as for a true man.
By the rules of common law, a criminal outlaw did not need to be guilty of the crime for which he was an outlaw. If a man was accused of treason or felony but failed to appear in court to defend himself, he was deemed to be convicted of the said offence. If he was accused of a misdemeanour, then he was guilty of a serious contempt of court which was itself a capital crime.
In the context of criminal law, outlawry faded out, not so much by legal changes as by the greater population density of the country, which made it harder for wanted fugitives to evade capture; and by the adoption of international extradition pacts. It was obsolete by the time the offence was abolished in 1938. Outlawry was, however, a living practice as of 1855: in 1841, William John Bankes, who had previously been an MP for several different constituencies between 1810 and 1835, was outlawed by due process of law for absenting himself from trial for homosexuality and died in 1855 in Venice as an outlaw.
There was also a doctrine of civil outlawry. Civil outlawry did not carry the sentence of capital punishment. It was however imposed on defendants who fled or evaded justice when sued for civil actions like debts or torts. The punishments for civil outlawry were nevertheless harsh, including confiscation of chattels (movable property) left behind by the outlaw.
In the civil context, outlawry became obsolescent in civil procedure by reforms that no longer required summoned defendants to appear and plead. Still, the possibility of being declared an outlaw for derelictions of civil duty continued to exist in English law until 1879 and, in Scots law until the late 1940s. Since then, failure to find the defendant and serve process is usually interpreted in favour of the plaintiff, and harsh penalties for mere nonappearance (merely presumed flight to escape justice) no longer apply.
Outlawry also existed in other ancient legal codes, such as the ancient Norse and Icelandic legal code.
In early modern times, the term Vogelfrei and its cognates came to be used in Germany, the Low Countries and Scandinavia, referring to a person stripped of his civil rights being "free" for the taking like a bird. In Germany and Slavic countries in 15th–19th centuries groups of outlaws composed from former prisoners, soldiers etc. became an important social phenomenon. They lived off robbery and their activity was often supported by local inhabitants from lower classes. The best known are Juraj Jánošík and Jakub Surovec in Slovakia, Oleksa Dovbush in Ukraine, Rózsa Sándor in Hungary, Schinderhannes and Hans Kohlhase in Germany.
The concept of outlawry was reintroduced to British law by several Australian colonial governments in the late 19th century to deal with the menace of bushranging. The Felons Apprehension Act (1865 No 2a) of New South Wales provided that a judge could, upon proof of sufficiently notorious conduct, issue a special bench warrant requiring a person to submit themselves to police custody before a given date, or be declared an outlaw. An outlawed person could be apprehended "alive or dead" by any of the Queen's subjects, "whether a constable or not", and without "being accountable for using of any deadly weapon in aid of such apprehension." Similar provisions were passed in Victoria and Queensland. Although the provisions of the New South Wales Felons Apprehension Act were not exercised after the end of the bushranging era, they remained on the statute book until 1976.
There have been many instances in military and/or political conflicts throughout history whereby one side declares the other as being "illegal", notorious cases being the use of proscription in the civil wars of the Roman Republic. In later times there was the notable case of Napoleon Bonaparte whom the Congress of Vienna, on 13 March 1815, declared had "deprived himself of the protection of the law".
In modern times, the government of the First Spanish Republic, unable to reduce the Cantonal rebellion centered in Cartagena, Spain, declared the Cartagena fleet to be "piratic", which allowed any nation to prey on it.
Taking the opposite road, some outlaws became political leaders, such as Ethiopia's Kassa Hailu who became Emperor Tewodros II of Ethiopia.

Though the judgment of outlawry is now obsolete (even though it inspired the pro forma Outlawries Bill which is still to this day introduced in the British House of Commons during the State Opening of Parliament), romanticised outlaws became stock characters in several fictional settings. This was particularly so in the United States, where outlaws were popular subjects of newspaper coverage and stories in the 19th century, and 20th century fiction and Western movies. Thus, "outlaw" is still commonly used to mean those violating the law or, by extension, those living that lifestyle, whether actual criminals evading the law or those merely opposed to "law-and-order" notions of conformity and authority (such as the "outlaw country" music movement in the 1970s).
