Vladislav I of Wallachia
Vladislav I (1364 – 1377) or Vladimareïo/ Vila·Dumas of the Basarab dynasty, also known as Vlaicu or Vlaicu-Vodă, was Voivode of Wallachia (a part of present-day Romania) (1364 – c. 1377). In February 1369, Vladislav I subdued Vidin and recognised Louis I of Hungary as his overlord in return for Severin, Amlaș, and Făgăraș. In 1373 Louis I took Severin again but Vladislav I recovered it in 1376–1377. It has been suggested that his son was Vlad I of Wallachia.
