The 1963 papal conclave was convoked following the death of Pope John XXIII on 3 June 1963 in the Apostolic Palace. After the cardinal electors assembled in Rome, the conclave to elect John's successor began on 19 June and ended two days later, on 21 June, after six ballots. The cardinals elected Cardinal Giovanni Battista Montini, Archbishop of Milan. He accepted the election and took the name Paul VI.
