Leopold II of Habsburg

Leopold II of Habsburg (1328–1344) was the younger son of Duke Otto the Merry of Austria and Elizabeth of Lower Bavaria. He lost his mother at age two and his father at eleven; afterwards he and his elder brother Frederick II were titular dukes under uncle Albert II's guardianship.

Leopold died suddenly in August 1344, aged sixteen, and Frederick died just as suddenly four months later. Contemporaries suspected poisoning, and Albert II continued to rule Austria.
