Proscription (Latin: proscriptio) is, in current usage, a "decree of condemnation to death or banishment" (OED) and can be used in a political context to refer to state-approved murder or banishment. The term originated in Ancient Rome, where it included public identification and official condemnation of declared enemies of the state. It has been used broadly since to describe similar governmental and political actions, with varying degrees of nuance, including the en masse suppression of ideologies and elimination of political rivals or personal enemies. In addition to its recurrences during the various phases of the Roman Republic, it has become a standard term to label:
Proscriptions (Latin proscriptio, plural proscriptiones) initially meant public advertisements or notices signifying property or goods for sale.
During the dictatorial reign of Sulla, the word took on a more sinister meaning. In 82 or 81 BC, Sulla instituted the process of proscription in order to avenge the massacres of Gaius Marius and Gaius Marius’ son. He instituted a notice for the sale of confiscated property belonging to those declared public enemies of the state (modern historians estimate about 520 people were proscribed as opposed to the ancient estimate of 4,700 people) and therefore condemned to death those proscribed, called proscripti in Latin.
There were multiple reasons why the ancient Roman government may have desired to proscribe or attribute multiple other forms of pain. One of the most prevalent reasons for punishment are treason crimes, also known as lex maiestatis. Treason crimes consisted of a very broad and large number of regulations, and such crimes had a negative effect on the government. This list includes, but is not limited to: assisting an enemy in anyway, Crimen Laesae Majestasis, acts of subversion and usurpation, offense against the peace of the state, offenses against the administration of justice, and violating absolute duties. Overall, crimes in which the state, emperor, the state’s tranquility, or offenses against the good of the people would be considered treason, and, therefore, would constitute proscription. Some of these regulations are understandable and comparable to safety laws within the United States today; however, others, like violating absolute duties, could very easily be accidents or circumstantial crises that would deserve punishment regardless.
