Balc (Hungarian: Balk)^[1] was, according to many historians (e.g., Alexandru Dimitrie Xenopol, Ştefan Pascu), the third voivode of Moldavia, ruling in ca. 1359 or 1364, but the sequence of the voivodes listed in the Romanian chronicles does not refer to him.^[2][3] He was the son of Sas, the second voivode of Moldavia.^[2]

Although Balc was the legitimate pretender to the throne, Bogdan, who had been voivode in Maramureș, crossed the Carpathian Mountains into Moldavia possibly immediately after the death of Sas, before Balc was able to consolidate his reign.^[2][3] In Moldavia, Bogdan joined local forces opposed to the Hungarian monarchy.^[3]

Balc fought valiantly at the head of his men, but he was severely wounded and lost several members of his family and retinue.^[2] Following his defeat, Balc fled Moldavia for Hungary.^[1]

According to a diploma issued on February 2, 1365, King Louis I of Hungary (1342–1382) gave Cuhea and other possessions in Maramureș to Balc and his brothers for their faith towards their sovereign and particularly for their devoted behavior in Moldavia.^[1] The domains around Cuhea had belonged to Bogdan, but the king had confiscated them in order to compensate Balc and his brothers for the loss of the state east of the Carpathians.^[2]

Later, Balc became the head of Szatmár (Sătmar), Ugocsa and Máramaros (Maramureș) counties in the Kingdom of Hungary, and he was also invested with the title of Count of the Székelys.^[4]
