Frederick the Fair, c.1286–1330, German antiking (1314–26), duke of Austria, son of Albert I, German king. On the death of Henry VII, Holy Roman emperor and German king, the split between the supporters of the houses of Hapsburg and Luxemburg resulted in the dual election (1314) of Frederick and Louis of Bavaria (Holy Roman Emperor Louis IV). War ensued and Frederick and his supporters were defeated (1322) by Louis at Mühldorf. However, the pope refused to confirm Louis as Holy Roman emperor, and Frederick remained a possible rival until his death.
