Louis I of Hungary
Bogdan and his retainers left Maramureș for Moldavia between 1359 and 1365. Moldavia had been under the rule of Sas of Moldavia, a vassal of Louis I of Hungary, but the local Vlachs were opposed to the Hungarian suzerainty. Bogdan expelled Sas's son, Balc, by force and seized the throne. In retaliation, Louis I confiscated Bogdan's estates in Maramureș in 1365. Bogdan reigned as the first voivode of Moldavia. He did not accept the overlordship of Louis I of Hungary, transforming Moldavia into the second independent Romanian principality.
