The cardinals are ordained bishops and Vatican officials of various nationalities, appointed by the Pope.Recognisable by their unique red vestments, their primary responsibility is to elect a new pope while also governing the Catholic Church in the interim before a new pope is announced.The governance is headed by the cardinal camerlengo also known as the chamberlain.
When a papal vacancy occurs due to the Pope’s death or resignation, the Cardinals are summoned to Vatican City for the papal election, known as the Conclave.Only cardinals under 80 can vote in the papal conclave meaning that they can also be elected pope but it’s not a guarantee for them.
