Konstanty Ostrogski

Duke of Ostrog, palatine of KievAlso: Konstantyn Vasyl Ostrozky, Constantine of Ostrog

Orthodox magnate of Poland-Lithuania, palatine of Kiev, who did not join the Union of Brest. Clement VIII was still urging him to accept it in 1605.

What this wiki reports of Ostrogski comes from a letter addressed to him by Clement VIII on 15 January 1605, headed to “Constantius, duke of Ostrog, palatine of Kiev”. The pope is replying to a letter of his. He takes up Ostrogski’s assertion that the bishops had brought the business of union to Rome in haste and without his knowledge, assures him that the rites and ceremonies of his church had been kept whole, and answers his plan to approach the patriarchs of Antioch and Constantinople by saying that this would be a long and laborious road for a man of his age; he urges the duke to lead by his own example and come into the Roman church (Clement VIII, letters, in Theiner, Vetera monumenta Poloniae, vol. 3, no. 229 (15 January 1605), pp. 286–287). The letter shows that more than eight years after the synod of Brest he had not accepted the union (Clement VIII, letters, in Theiner, Vetera monumenta Poloniae, vol. 3, no. 229 (15 January 1605), pp. 286–287). See the Union of Brest.

    The Union of Brest

    In 1595 the metropolitan of Kiev and most of his bishops, Orthodox subjects of the Polish king, offer union with Rome on thirty-three conditions. Clement VIII receives them, and the union is proclaimed at Brest in 1596. Other bishops and Prince Ostrogski stay outside it.
