In nomine Domini, named for its Latin incipit ("In the name of the Lord"), is a papal bull of Pope Nicholas II and canon of the Council of Rome, promulgated on April 13, 1059, establishing cardinal-bishops as the sole electors of the pope, with the consent (as determined by the cardinal-bishops) of cardinal-deacons and cardinal-priests (followed by the laity and the Holy Roman Emperor), which laid the groundwork for the hierarchical preeminence of cardinals within the Roman Catholic Church. Suffrage was extended to all cardinals during the schism of Antipope Clement III in 1084, and the co-operation of the inferior clergy was dispensed with in 1189, beginning the establishment of the College of Cardinals, which did not fully come into force until the election of Pope Innocent II in 1130.
