papal conclave
Cardinals assembled inside the Sistine Chapel of the Vatican Palace for a conclave to elect a new pope; Vatican City, 2005.
In 1059, Pope Nicholas II issued a landmark decree to reform papal elections, aiming to eliminate lay interference and protect the papacy from the influence of powerful Roman families.123
The key components of this reform included:
- Electoral Authority: The right and duty to elect the pope were vested in the cardinal bishops, who were to choose a candidate and then summon the remaining cardinals to participate.14
- Clerical and Lay Involvement: The decree required the assent of cardinal priests and deacons, followed by the acclamation of the Roman clergy and people.14
- Imperial Role: The decree sought to restrict imperial interference, though it still acknowledged a vague role for the German king to confirm the electionāa right that was not hereditary and required papal validation.24
By organizing the cardinals into a formal advisory body, this decree laid the foundation for the Sacred College of Cardinals and served as a critical step in establishing the independence of the church during the Gregorian Reform movement.254
