(1122) Compromise between Pope Calixtus II and Emperor Henry V (r. 110625) to settle the Investiture Controversy , reached at Worms, Germany.
It marked the end of the first phase of conflict between Rome and what was becoming the Holy Roman Empire and made a clear distinction between the spiritual side of a prelate's office and his position as a landed magnate and vassal of the crown. Bishops and abbots were to be chosen by the clergy, but the emperor was to decide contested elections. Those selected were to be invested first with the powers and privileges of their office as vassal (granted by the emperor) and then with their ecclesiastical powers and lands (granted by church authority).
