Saint Vincent Ferrer, (In Valencian Sant Vicent Ferrer) (1357 - April 5, 1419) was a Valencian Dominican missionary; born in Valencia, Kingdom of Valencia (nowadays, Spain).
He was depressed because of the great schism and was close to death at the age of forty, but was supposedly healed by the Lord who instructed him to go out and convert many sinners. For twenty-one years, he was said to have traveled to Aragon, Castile, Switzerland, France, Italy, England, Ireland, and Scotland, preaching the gospel and converting many sinners.
He is also well known in Spain for his intervention during the political discussion known as the Caspe Compromise, a debate by which the succession of the King of Aragon was solved giving the throne to a Castilian prince: this would later help the union of the crowns of Castile and Aragon, approximately corresponding to today's Spain's territory.
Saint Vincent died on the 5th of April, 1419 at Vannes, Brittany, France. His feast day is celebrated on the 5th of April.
