Frederick the Fair

Frederick the Fair (1289–1330), second son of Albert I, ruled Austria and Styria from 1308. After Henry VII died in 1313, the electors chose Frederick and his cousin Louis of Bavaria as rival kings in 1314. In 1315 he married Isabella, daughter of James II of Aragon.

Defeated and captured at the Battle of Mühldorf in 1322, he was held prisoner for three years. The 1325 Treaty of Munich made him Louis's co-king, though he never held real power. He died at Gutenstein in 1330, succeeded by his brothers Albert II and Otto.
