Pope Francis's death at the age of 88 means the Catholic Church must choose a new leader. Here's how cardinals elect the next pontiff at the conclave.

Pope Francis, the 266th pope of the Roman Catholic Church, will be mourned and buried at the Basilica of Saint Mary Major after dying one week ago at 88 years old.
