Fürstbistum Ermland
After finishing his duties at Constance, in the summer of 1418 Abezier was formally enthroned as the see of the Prince-Bishopric of Warmia—whose seat was at Heilsberg—, as Prince-Bishop over this territory. His election of 1415 had been unanimous. By then, the territory had been left much destroyed, by the war between both nations. Abezier remained at Heilsberg as the bishop of Ermland, until his death, on February 11, 1424.
