Latrocinium (from Latin latro, "bandit", ultimately from Greek latron, "pay" or "hire" [1]) was a war not preceded by a formal declaration of war as understood in Roman law; thus guerrilla warfare conducted against Rome was a form of latrocinium. [2] It is typically translated into English as " banditry" or " brigandage", but in antiquity encompassed a wider range of subversive or anti-authoritarian actions, especially slave rebellions organized under charismatic leaders. [3] In designating acts of violence that have ideological motives instead of or in addition to material gain, the modern distinction between terrorism and war may be a more illuminating comparison for the 21st century. [4] The Greek term was leisteia; Plato and Aristotle regarded banditry as a way of life, like fishing or hunting. [5]
In ecclesiastical Latin, latrocinium is a term of abuse for ecumenical councils regarded as renegade or subversive of canon law, especially the second Council of Ephesus – dubbed the "Robber Council". (Latrocinium Ephesinum) in 449. [6] The Third Council of Sirmium in 357, the Council of Hieria in 754, and the Synod of Pistoia in 1786, were also each described by their opponents as a latrocinium. Some also regarded the fourth Council of Constantinople (879–880) as a latrocinium. [7]
In the Middle Ages, latrocinium was a war without just cause, or piracy. [8]
