Christianization of Lithuania - Aftermath

Aftermath

Ethnic Lithuanian nobles were the main converts to Catholicism, but paganism remained strong among the peasantry. Pagan customs prevailed for a long time among the common people of Lithuania and were covertly practiced. There had been no prosecution of priests and adherents of the old faith. However, by the 17th century, following the Counter-Reformation (1545-1648), the Roman Catholic faith had essentially taken precedence over earlier pagan beliefs.

The conversion and its political implications had lasting repercussions for the history of Lithuania. As the majority of the population of the Grand Duchy of Lithuania outside Lithuania proper was Orthodox and the elite gradually converted to Roman Catholicism, religious tensions increased. Some of the Orthodox Gediminids left Lithuania for Muscovy, where they gave rise to such families as the Galitzine and the Troubetzkoy. The Orthodox population of present-day Ukraine and eastern Belarus often sympathized with the rulers of Muscovy, who portrayed themselves as the champions of Orthodoxy. These feelings contributed to such reverses as the Battle of Vedrosha, which crippled the Grand Duchy and undermined its position as a dominant power in Eastern Europe.

On the other hand, the conversion to the Roman Catholicism facilitated Lithuania's integration into the cultural sphere of Western Europe and paved the way to the political alliance of Lithuania and Poland, finalized as the Union of Lublin in 1569.
