Nicholas Alexander of Wallachia

Nicholas Alexander (c. 1300–1364), son of Basarab I, was the second voivode of Wallachia and is best known for founding the Orthodox Metropolis of Ungro-Wallachia in 1359.

He became his father's co-ruler about 1344 and swore loyalty to Louis I of Hungary to head off an invasion, ruling alone after Basarab's death in 1351 or 1352. At first he resisted Hungarian pressure, but in 1354, threatened by the Golden Horde, he recognised Louis's suzerainty and admitted Catholic missions and Saxon merchants; in 1359 he cast off Hungarian overlordship.

He died on 16 November 1364 and was buried at Câmpulung, his epitaph calling him the great and sole ruler, son of great Basarab. His son Vladislav I succeeded him.
