William Drugeth, an influential advisor of Louis's late father, died in September 1342. He bequeathed his landed property to his brother, Nicholas, but Louis confiscated those estates. In late autumn, Louis dismissed his father's Voivode of Transylvania, Thomas Szécsényi, although Szécsényi's wife was a distant cousin of the queen mother. Louis especially favored the Lackfis: eight members of the family held high offices during his reign. Andrew Lackfi was the commander of the royal army during the first war of Louis's reign. In late 1342 or early 1343, he invaded Serbia and restored the Banate of Macsó, which had been lost during his father's reign.
