The Gregorian Reform movement was rather a series of movements many of which involved the reform of the Catholic Church, headed by Gregory VII, formerly the Archdeacon Hildebrand. Gregory became Pope in 1073 with the objective of reforming not the body of the church, but a purification of the clergy in general. Gregory is perhaps most recognized with the quarrel between himself and King Henry IV of Germany, known as the "Investiture Contest". Gregory's "Dictus Pape" outlines his policies and ideals, as well as those of the Catholic Church. In this work, Gregory claims that the pope has power to depose and restore bishops, and also effectively reduces the authority of other bishops. This doctrine supported the idea that Rome and the church here also afforded primacy over all other churches. Gregory's papacy also bolstered the power of the Church over that of the State. The Gregorians defended the ideal of a separation of powers, claiming "Let kings have what belongs to kings, and priests have what belongs to priests." The Petrine primacy was now more affirmed than ever.
