Also known as Radu Voda. According to the legend, Radu Negru is described as "hailing from Fagaras" in Southern Transylvania. He was born sometime in the late 1260s and migrated south with fellow Wallachian boyars, clergy and peasants around 1290 due to his disdain of Hungarian rule, where he would found the Wallachian state and its first ruling dynasty. He settled Campulung and Curtea de Arges, building important churches and fortification, as well as uniting local Vlach knezes under his authority. He would hold the Wallachian throne until 1304, after which Basarab I of Wallachia would usurp him in the following years.
