Pope Martin V (b. 1368)
Pope Martin V (Latin: Martinus V; Italian: Martino V; January/February 1369 – 20 February 1431), born Otto (or Oddone) Colonna, was the head of the Catholic Church and ruler of the Papal States from 11 November 1417 to his death in 1431. His election effectively ended the Western Schism of 1378–1417. He is the last pope to date to take on the pontifical name "Martin".
