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. Early life As was the custom of this time, John is denoted by the village of Capestrano, in the Diocese of Sulmona, in the Abruzzi region, Kingdom of Naples. His father had come to Italy with the Angevin court of Louis I of Anjou, titular King of Naples. He studied law at the University of Perugia. In 1412, King Ladislaus of Naples appointed him Governor of Perugia, a tumultuous and resentful papal fief held by Ladislas as the pope's champion, in order to effectively establish public order. When war broke out between Perugia and the Malatestas in 1416, John was sent as ambassador to broker a peace, but Malatesta threw him in prison. It was during this imprisonment that he began to study theology. When he was released in he decided to give up the world and become a Franciscan friar, citing a dream where Saint Francis of Assisi ordered him to enter the Order. He had married before the war, but asserted the marriage was never consummated and received permission to take holy orders. Friar and preacher Together with James of the Marches, John entered the Order of Friars Minor at Perugia on 4 October 1416. Along with James, he studied theology at Fiesole, near Florence, under Bernardine of Siena. He soon gave himself up to the most rigorous asceticism, violently defending the ideal of strict observance and orthodoxy, following the example set by Bernardine. From 1420 onwards, he preached with great effect in numerous cities and eventually became well known. He was ordained in 1425. Unlike most Italian preachers of repentance in the 15th century, John was effective in northern and central Europe—in German states of Holy Roman Empire, Bohemia, Moravia, Austria, Hungary, Croatia and the Kingdom of Poland.
