St. John of Capistrano (24 June 1386 – 23 October 1456) was a Franciscan friar and Catholic priest from the Italian town of Capestrano, Abruzzo. Famous as a preacher, theologian, and inquisitor, he earned himself the nickname “the Soldier Saint” when in 1456 at age 70 he led a crusade against the invading Ottoman Empire at the siege of Belgrade with the Hungarian military commander John Hunyadi.
Elevated to sainthood, he is the patron saint of jurists and military chaplains, as well as the namesake of the Franciscan missions San Juan Capistrano in Southern California and San Juan Capistrano in San Antonio, Texas.
