Polish-Lithuanian Uniate project at the Council of Constance

Abstract

Unions initiative early 15 th c. provided the Ukrainian Church participated in the
broad church forum, where discussed inter-church agreement. Until now we can not
give a clear answer as to how sincere efforts were Metropolitans of Kiev and Polish
and Lithuanian rulers to a combination of Catholic and Orthodox Churches. Con-
fronting the Kingdom of Poland and Lithuanian principalities of the Teutonic Order
allows us to consider the uniate initiatives and projects from a different angle.
