Cardinal electors for the 1939 conclave

The papal conclave of 1939 was convened to elect a pope, the leader of the Catholic Church, to succeed Pope Pius XI following his death on 10 February 1939. The time period between the previous pope's death and the start of the conclave had been extended by Pius XI's motu proprio, Cum proxime, following the late arrival of several electors in the previous conclave.
