Leopold II, Duke of Austria (1328 â 10 August 1344), a member of the House of Habsburg, was a titular Duke of Austria and Styria from 1339 until his death.
Leopold was the younger son of Duke Otto the Merry and his first wife Elizabeth of Bavaria, a daughter of Stephen I, Duke of Bavaria by his marriage to Jutta of Schweidnitz. His elder brother was Frederick (1327âÂÂ1344).
Otto the Merry had ruled the Habsburg lands jointly with his elder brother Albert II. When Otto died at Neuberg Abbey on 17 February 1339, Leopold and Frederick became titular Dukes of Austria, though both were minors and their uncle Albert II continued as the effective ruler of the Habsburg domains.
On 10 August 1344, at the age of sixteen, Leopold died suddenly. Four months later, on 11 December 1344, his brother Frederick also died equally suddenly. In both cases, there were suspicions of poisoning. The beneficiary of their deaths was their uncle Albert II, who thereafter ruled Austria alone until his own death in 1358.
