John of Ragusa

John of Ragusa (Croatian: Ivan Stojković; born c. 1380 at Dubrovnik, Republic of Ragusa) was a Croatian Dominican theologian. He died at Lausanne, Switzerland in 1443.

He was president of the Council of Basle, and a legate to Constantinople. He was created cardinal by Antipope Felix V, so would be considered by many a "pseudocardinal".
