Following the death of Pope Francis, the Catholic Church has chosen a date to elect its new leader, in a process virtually unchanged in 800 years.The system is known as the ‘Papal Conclave,’ and is a democratic process with a strong emphasis on working through multiple rounds of voting until a clear consensus emerges.

Pope Francis' death sets into motion a series of formalized rites and observances that occur during what is called the interregnum, which begins upon the pontiff's passing and ends with the election of his successor. The period of time during which the papacy is vacant is known as the sede vacante, Latin for "vacant seat."
