Abstract

The author of this article considers the Brest Union and the emergence of the Uniate Church as a kind of product of the national-cultural and religious-church processes that were experienced by Europe, and with it Ukraine in the second half of the XVII - the first half of the XVII century. The author argues that the union of the Kievan Metropolitanate with the Roman Apostolic See in 1596 fully fits into the European-wide reformational context, when the formation of national local churches was a priority task.
