Louis and the royal army stayed in Transylvania in November 1359 and January 1360, implying that he planned a military expedition against Wallachia or another neighboring territory. A charter of 1360 said that a Romanian voivode, Dragoș of Giulești, restored Louis's suzerainty in Moldavia after a rebellion of local Romanians. According to most Moldavian chronicles, Dragoș, who is sometimes identified with Dragoș of Giulești and sometimes as Dragoș of Bedeu, departed from the Hungarian country, from Maramureș at the head of his retinue, crossed the Carpathian Mountains while chasing an aurochs and settled in the valley of the Moldova River in 1359. The same chronicles presented this dismounting by Dragoș as a decisive step towards the development of the Principality of Moldavia. Another Romanian voivode, Bogdan, who had rebelled against Louis and plundered the estates of the Romanian landowners loyal to the king already in the 1340s, departed from Hungary and invaded Moldavia in the early 1360s. Bogdan expelled the descendants of Louis's vassal, Dragoș, from the principality. According to John of Küküllő, Louis launched several expeditions against Bogdan, but their dates cannot be determined. Bogdan ruled Moldavia as an independent prince.
