In nomine Domini is a papal bull written by Pope Nicholas II. The bull was issued on 13 April 1059 and caused major reforms in the system of papal election, most notably establishing the cardinal-bishops as the sole electors of the pope, with the consent of minor clergy.
Robert Guiscard is proclaimed by Pope Nicholas II as a duke as the cardinal-bishops look on.
A papal conclave is a gathering of the College of Cardinals convened to elect a bishop of Rome, also known as the pope. Catholics consider the pope to be the apostolic successor of Saint Peter and the earthly head of the Catholic Church.
The 1492 papal conclave was the first to be held in the Sistine Chapel, the site of all conclaves since 1878.
Since the conclave of 2005, the cardinals electors reside in the Domus Sanctae Marthae for the length of the conclave.
