Synod of Worms

The Synod of Worms was an ecclesiastical synod (and Imperial Diet of the Holy Roman Empire) convened by the Emperor Henry IV in January 1076, at Worms, Germany. It was intended to agree a condemnation of Pope Gregory VII, and Henry's success in achieving this outcome marked the beginning of the Investiture Controversy.
