The Peace and Truce of God (Latin: Pax et treuga Dei; German: Gottesfrieden; French: Paix de Dieu; Catalan: Pau i Treva de Déu) was a movement in the Middle Ages led by the Catholic Church and the first mass peace movement in history. The goal of both the Pax Dei and the Treuga Dei was to limit the violence of feuding endemic to 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.
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 survived in some form until the thirteenth century.
