Vladislav II of Wallachia
Vladislav II (died 20 August 1456) was a voivode of the principality of Wallachia, from 1447 to 1448, and again from 1448 to 1456. The way Vladislav II came to the throne is debatable. The most accepted view is that Vladislav assassinated Vlad II Dracul, ruler of Wallachia, and was subsequently placed on the throne by John Hunyadi, on the other, Vladislav II was helped by the Ottomans to replace Dan III which was assigned by the Hungarians.
