The most accepted view is that Vladislav assassinated Vlad II Dracul, ruler of Wallachia, and was subsequently placed on the throne by John Hunyadi,[1][full citation needed] on the other, Vladislav II was helped by the Ottomans to replace Dan III which was assigned by the Hungarians.
It is certain, however, that he did not send any troops in aid and as a result, John Hunyadi took back the Transylvanian possessions of Făgăraș and Amlaș on 23 April 1452.
Vladislav retaliated by embargoing all Wallachian trade to Brașov County, then part of Hunyadi's Transylvania.
However, on 15 November 1455, after Hunyadi informed the people of Brașov that the embargo would be lifted, Vladislav seized back Transylvanian possessions, and attacked the Făgăraș fortress and in the process burns a few Saxon villages.
Vladislav founded the Snagov Monastery in 1453, where a wooden sculpted door has been preserved to this day, and is exhibited at the Religious Art Museum of Bucharest.
