Truce of God.
In 1040 the Church forbade the barons to make any attack on each other between sunset on Wednesday and sunrise on the following Monday, or upon any ecclesiastical fast or feast day. It also provided that no man was to molest a labourer working in the fields, or to lay hands on any implement of husbandry, on pain of excommunication. (See PEACE OF GOD.)
