The selection of a new pope is a centuries-old tradition in the Catholic Church. The process is called “conclave,” meaning “with key” in Latin, and has its roots in the Middle Ages. Cardinals who participate in the conclave follow an elaborate procedure that has been refined over time.
In 1996, Pope John Paul II oversaw a significant overhaul of the rulebook, known as “Universi Dominici Gregis.” This document outlines the modern rules for cardinals to follow during the conclave. Benedict XVI made further adjustments in the years following his papacy.
Once a date is set, the cardinal electors gather at the Sistine Chapel within the Vatican. To be elected pope, a candidate must receive two-thirds of the votes cast. The process involves solemn oaths and intricate voting procedures, culminating in the release of white smoke signaling the election.
After the new pope’s selection, he emerges onto the balcony to deliver his first “Urbi et Orbi” blessing, marking the end of the conclave. The days ahead will see the new pope attend an inauguration Mass at St. Peter’s Basilica and assume his duties as the leader of the Catholic Church.
