A new pope will be selected to lead the Catholic Church following the death of Pope Francis. The pope is chosen during a highly secretive election called a conclave. Francis, 88, died on April 21. The pope will be honored with a nine-day mourning period known as the Novendiale, a tradition that began in Ancient Rome.

Traditionally, the pope's internment, which takes place between four and six days following his death, occurs after a traditional Roman Catholic funeral Mass officiated by the dean of the College of Cardinals. The pope is then entombed in the grottoes below St. Peter's Basilica with three coffins: one made of cypress, one of lead and one of oak.
