Vladislav I of Wallachia

Vladislav I of the Basarab dynasty, also known as Vlaicu or Vlaicu-Vodă, was the Voivode of Wallachia between 1364 and 1377. He was the son of Nicholas Alexander of Wallachia and Clara Dobokai.

In February 1369, Vladislav I subdued Vidin and recognised Louis I of Hungary as his overlord, in return for Severin, Amlaș, Făgăraș and 120,000 ducats. In 1373, Louis I took Severin again, but Vladislav I recovered it, in 1376–1377.
