Abraham Woyna

Abraham Woyna (Wojna; Abraomas Vaina) (1569–1649) was a Roman Catholic priest and auxiliary bishop of Vilnius (1611–1626), bishop of Samogitia (1626–1631) and then bishop of Vilnius (1631–1649). His term in office was marked by the rise of Calvinism in the Polish–Lithuanian Commonwealth, to which he was actively opposed.

Among his achievements was the foundation of the monasteries of the Discalced Carmelites and the Good Friars in Vilna (modern Vilnius, Lithuania), the latter of which also opened up a hospital and a pharmacy nearby. He also led the anti-Protestant faction in the local politics and led the persecution of the Calvinist activists.
