Vladislav I of Wallachia

Vladislav I, called Vlaicu Vodă, was voivode of Wallachia from 1364 until his death in 1377, succeeding his father Nicholas Alexander. Around 1365 he became the first Wallachian ruler to mint silver coins. In 1366 he accepted Louis I of Hungary as overlord and received Severin and Făgăraș.

He later fought the Hungarians and occupied Vidin in 1369 before submitting to Louis again. In 1369 he defeated a Turkish army allied with Bulgaria, securing its Danube frontier. He also backed the Vodița and Tismana monasteries.
