his daughter Margaret off to King John's son John Henry. Since he was the last male heir of the Tyrolean branch of the Meinhardiner dynasty, he attempted to maintain their possessions, but ultimately failed. Even though Emperor Louis IV, in return for Henry's mediation in the dispute with Frederick the Fair, had assured him in 1330 that his daughter could succeed him, Louis reneged on his promise in a secret treaty with the House of Habsburg in the same year. After Henry's death in 1335, the Habsburg duke Albert II of Austria and his brother Otto took control of Carinthia and Carniola. Henry's daughter Margaret could only succeed him in Tyrol with the support of the local nobles; however, in 1363 she ultimately had to bequeath her lands to Albert's II son Duke Rudolf IV of Austria as well. The Gorizia branch of the Meinhardiner dynasty ruled their county until the extinction of the line in 1500, after which the estates likewise fell to the Habsburgs. Marriage and issue Henry was married three times: In 1306, he married Anna Přemyslovna (1290–1313). This marriage produced no children. In 1313, he wed Adelaide of Brunswick (1285 – 16 August 1324), daughter of the Welf duke Henry I of Brunswick-Grubenhagen. This marriage produced two daughters: Adelaide (1317–25 May 1325). Margaret "Maultasch" (1318 – 3 October 1369, Vienna), Countess of Tyrol from 1335 to 1363. In 1327, he married Beatrice (1310–1331), daughter of Count Amadeus V of Savoy. This marriage produced no children.
