Lynching is an extrajudicial punishment by an informal group. It is most often used to characterize informal public executions by a mob in order to punish an alleged transgressor, or to intimidate a group. It is an extreme form of informal group social control such as charivari, skimmington, riding the rail, and tarring and feathering, but with a drift towards the display of a public spectacle. It is to be considered an act of terrorism and punishable by law. Instances of it can be found in societies long antedating European settlement of North America.
In the U.S. most perpetrators of lynchings were white and the victims black. The political message—the promotion of white supremacy and black powerlessness—was an important element of the ritual, with lynchings photographed and published as postcards which were popular souvenirs in the U.S. As well as being hanged, victims were sometimes burned alive and tortured, with body parts removed and kept as souvenirs.
The origins of the word "lynch" are obscure, but it likely originated during the American revolution. The verb comes from the phrase "Lynch Law", a term for a punishment without trial. Two Americans during this era are generally credited for inventing the phrase: Charles Lynch and William Lynch, who both lived in Virginia in the 1780s. Charles Lynch has the better claim, as he was known to have used the term in 1782, while William Lynch isn't known to have used the term until much later. There is no evidence that death was imposed as a punishment by either of the two men. In 1782, Charles Lynch wrote that his assistant had administered "Lynch's law" to Tories "for Dealing with Negroes, &c."
In the United States, the origin of the terms lynching and lynch law is traditionally attributed to a Virginia Quaker named Charles Lynch.Charles Lynch (1736–1796) was a Virginia planter and American Revolutionary who headed a county court in Virginia which incarcerated Loyalist supporters of the British for up to one year during the war. While he lacked proper jurisdiction, he claimed this right by arguing wartime necessity. Subsequently, he prevailed upon his friends in the Congress of the Confederation to pass a law which specifically exonerated him and his associates from wrongdoing. He was concerned that he might face legal action from one or more of those so incarcerated, even though the American Colonies had won the war. This move by the Congress provoked controversy, and it was in connection with this that the term "Lynch law", meaning the assumption of extrajudicial authority, came into common parlance in the United States. Lynch was not accused of racist bias, and indeed acquitted blacks accused of murder on three separate occasions, as dictated by the facts brought before him. He was accused, however, of ethnic prejudice in his abuse of Welsh miners.
