Constantine Czartoryski

Constantine (died c. 1390), by tradition a son of Algirdas of Lithuania, was a Gediminid prince and founder of the Czartoryski family. He led a Lithuanian banner at the Battle of Blue Waters in 1362, which broke the Golden Horde and won Podolia for Lithuania. Made the first prince of Podolia and ruling from Smotrych, he struck his own coinage bearing Saint George.

After Jogaila accepted the Union of Krewo in 1385, Constantine withdrew to Hungary, where he died between 1388 and 1392. His sons founded the Czartoryski line.
