Pope Leo XIII

Pope Leo XIII (Italian: Leone; born Vincenzo Gioacchino Raffaele Luigi Pecci) was head of the Catholic Church from 20 February 1878 to his death. He was the oldest pope (reigning until the age of 93), and had the third longest confirmed pontificate, behind that of Pius IX (his immediate predecessor) and John Paul II. He is the most recent pontiff to date to take the pontifical name of "Leo" upon being elected to the pontificate.
