Poland Church History

Research procedures and genealogical sources are different for each religion. It is helpful to understand the historical events that led to the creation of records your family was listed in, such as parish registers.

Roman Catholic (rzymsko-katolicki)
The Roman Catholic faith was accepted in Poland in A.D. 966 (the date considered to be the founding of Poland) and became the predominant faith in Poland by 1573. Although Protestantism made some inroads in the 1700s, Catholicism has remained the dominant religion of Poland.

Greek Catholic (grecko-katolicki)
In 1595 Orthodox Ukrainians were formally brought into union with the Roman Catholic Church. They retained their orthodox liturgy and doctrine but recognized the authority of the Roman Catholic pope. This church is generally found in the southeast area of Poland. Many Greek Catholics affiliated with either the Russian Orthodox or the Roman Catholic church after they emigrated to the United States.

Russian Orthodox (prawosławny)
The Russian Orthodox faith stems from the Byzantine Church, which split with the Roman Catholic Church in 1054. Russian Orthodoxy gained a limited foothold in Congress Poland during Russia’s control. Its members in Poland were predominantly of Russian or Belorussian ethnic background.

Protestant (ewangelicki)
Because Poland is predominantly Catholic, many religious groups were severely persecuted until the Warsaw Confederation in 1573, when toleration laws were passed and the various Christian denominations were assured protection by the state. Thereafter, Poland became a haven for people who were persecuted elsewhere. Many persecuted Protestant groups were offered safe shelter in Poland, including Anabaptists, Bohemian Brethren, and others. Mennonites, Baptists, Brethren, Calvinists, and other groups have existed in Poland since the mid-1500s.

Calvinism, or the Evangelical Reformed Church, gained some followers among the Polish gentry. A few Calvinist Swiss refugees settled in Poland quite early. Most Calvinists in Poland were limited to ethnic Swiss Germans and were far fewer in number than the Lutherans.

Although Lutheranism (the Augsburg Confession or Evangelical Church) had only a small following in Poland, they did become firmly established among the German population. The Prussian provinces of Pomerania, Brandenburg, and East Prussia were settled by Germans from the 11th through the 13th centuries, and by 1880 Lutherans comprised 94% of the population of Brandenburg, 97% of Pomerania, and 86% of East Prussia.

At the partitions of Poland in 1772–95, Prussia gained the provinces of Silesia, Posen, and West Prussia, and German Lutherans began colonizing these previously Polish territories. By 1880 just under half of the population of Silesia and West Prussia and a third of the population of Posen was Lutheran. When parts or all of these Prussian territories became part of Poland at the end of World Wars I and II, most of the German Lutherans moved west into Germany.

Lutheran Germans also settled in other Polish territory taken by Prussia in 1795. This area of central Poland was for a time called South Prussia. It was incorporated into the Duchy of Warsaw from 1806–15 and became part of Congress Poland in 1815. Some of the Germans in this area remained in the Russian held parts of Poland, and others moved further east to Volhynia in Western Ukraine. In the late 1800s, when conditions worsened for these German colonists, many moved to German settlements near the Black Sea, to Germany, or to the United States.
