For nearly 180 years, papal conclaves have chosen a new pope in three to five days. In centuries past, they've taken a lot longer.

Cardinals have no contact with the outside world after the master of liturgical ceremonies utters the words “Extra Omnes” the Latin phrase for “all out,” to ask all those present except the cardinal electors to leave the Sistine Chapel to begin the voting process.

Cardinal Angelo Becciu, 76, announced Tuesday that he will not take place in the conclave to select the next pope following the death of Pope Francis.
