Pope Leo XIV, whose real name is Robert Francis Prevost, was born in Chicago in 1955 and was elected as the current pope in May 2025. He is the first American pope in history, making him the 267th pope overall. Born a citizen of Peru, where he served as Bishop of Chiclayo, he holds degrees from Villanova University, the Catholic Theological Union of Chicago, and the Pontifical University of Saint Thomas Aquinas.
