The Peace and Truce of God (Latin: Pax et treuga Dei) was a movement in the Middle Ages led by the Catholic Church and was one of the most influential mass peace movements in history. The goal of both the Pax Dei and the Treuga Dei was to limit the violence of feuding in the western half of the former Carolingian Empire – following its collapse in the middle of the 9th century – using the threat of spiritual sanctions. The eastern half of the former Carolingian Empire did not experience the same collapse of central authority, and neither did England. This movement was also marked by popular participation, with many commoners supporting the movement as a solution to the famines, violence, and collapse of the social order around them.
The Peace of God was first proclaimed in 989, at the Council of Charroux. It sought to protect ecclesiastical property, agricultural resources and unarmed clerics. The Truce of God, first proclaimed in 1027 at the Council of Toulouges, attempted to limit the days of the week and times of year that the nobility engaged in violence. The movement persisted in some form until the thirteenth century.
