Твртко I
Louis stayed in Transylvania between June and September 1366, implying that he waged war against Moldavia. He issued a decree authorizing the Transylvanian noblemen to pass judgments against "malefactors belonging to any nation, especially Romanians". He also decreed that testimony of a Romanian knez who had received a royal charter of grant weighed the same as that of a nobleman. In the same year, Louis granted the Banate of Severin and the district of Fogaras to Vladislav Vlaicu of Wallachia, who had accepted his suzerainty. Tvrtko I of Bosnia also accepted Louis's suzerainty after Hungarian troops assisted him in regaining his throne in early 1367.
