Personal union between the Kingdom of Hungary and the Kingdom of Poland was achieved twice: under Louis I of Hungary, in 1370–1382, and under Władysław III of Poland in 1440–1444. An earlier union was also accomplished by Wenceslaus III of Bohemia for a few months in 1305, although he was heavily resisted by local nobles in both kingdoms, and gave up the Hungarian crown soon after.
