Slavic Catholic

Slavic Catholic (or Catholic Slavs) are terms used for the predominantly Catholic Slavic nations and the history of Catholicism among the Slavic peoples; especially amongst the Western Slavs. The Catholic Slavic nations include all West Slavs (Poles, Czechs and Slovaks) as well as Slovenes and Croats.

Grand Duke Kazimierz IV of Lithuania and Poland (r. 1440–92) initiated the Catholicization of Kiev (which was Orthodox) early in his reign.

The Union of Brest (1596) saw the official establishment of the Uniate Church (Orthodox but Catholic in allegiance) in the Grand Duchy of Lithuania.

The Habsburg Monarchy launched a programme of re-Catholicization in Bohemia and Moravia in the 1620s. The Serbian Orthodox Eparchy of Marča became Uniate in 1611, although it was part of a conflict between local Catholic and Orthodox clergy over the century.
