of intensive settlements began in Banat, Transylvania and other regions within the Kingdom of Hungary after the withdrawal of the Mongols. King Béla IV was also considering settling the Knights Hospitallers in the lands between the Carpathians and the Lower Danube. His diploma of 1247 for the Knights evidences the existence of four Romanian polities in the region. They were under the rule of voivodes Litovoi and Seneslau, and of knezes Farcaş and John. Internal conflicts characterized the last decades of the 13th century in the Kingdom of Hungary. For instance, a feud between King Béla and his son, Stephen caused a civil war which lasted from 1261 to 1266. Taking advantage of the emerging anarchy, Voivode Litovoi attempted to get rid of the Hungarian monarchs' suzerainty in the 1270s, but he fell in a battle while fighting against royal troops. One of his successors, Basarab I of Wallachia was the first Romanian monarch whose sovereignty was internationally recognized after his victory over King Charles I of Hungary in the Battle of Posada of 1330.
