Blaise Magyar Blaise Magyar (Hungarian: "Magyar Balázs" ), also Blaž the Magyar, was a military commander and great officer of state in the Kingdom of Hungary in the 15th century. His military career started under the command of John Hunyadi. In the reign of John Hunyadi's son, Matthias Corvinus, he was Ban of Croatia from 1470 to 1472 and in 1483, Ban of Slavonia between 1470 and 1471 and in 1483, Ban of Bosnia from 1470 to 1471, and Voivode of Transylvania between 1472 and 1475.

Conrad I, Duke of Bohemia Conrad I of Brno (Czech: "Konrád I. Brněnský" ) (died 6 September 1092) was the duke of Bohemia for eight months in 1092. He was the brother and successor of Vratislaus II (died 14 January 1092) as the third son of Bretislaus I and Judith of Schweinfurt. He did not succeed as king, because his brother had only been elevated to the royal dignity for life by the Emperor Henry IV without the establishment of a hereditary monarchy.
