Isabella of Aragon

Isabella of Aragon (1302–1330) was a daughter of James II of Aragon and Blanche of Anjou. She married Frederick I of Austria in 1315. Frederick had been elected German king in 1314 in rivalry with Louis IV of Bavaria, so Isabella became queen of a divided Germany.

The rivals made peace in 1325 and ruled jointly until Frederick retired to Austria and died in 1330. Blind for her last six years, Isabella died that July and was buried at the Franciscan church in Vienna.
