In 1042 William held a church council in Normandy. At that council the church made a new law called the Truce of God. It was to help stop all the private wars. There could be no fighting on feast days or fast days. No fighting was allowed from Thursday night until Monday morning. The punishment for breaking the truce was excommunication. William probably reached the age of majority in about 1044. He no longer needed tutors. He could now rule on his own.
