Career
He was the Grand Marshal of Lithuania, Voivode of Navahrudak (1464–1471), first Voivode of Kiev (1471–1475) and Voivode of Trakai (1480–1483). Residents of Kiev resented the appointment of a Roman Catholic as voivode and refused to let him in. In exchange, Kiev acquired the status of a voivodeship, equal to that of Trakai and Vilnius and the subsequent voivodes were Orthodox nobles.
