Christianization of Poland
Conversion of country to Christianity
The Christianization of Poland (Polish: chrystianizacja Polski [xrɘs.tja.ɲiˈza.t͡sja ˈpɔl.ski]) refers to the introduction and subsequent spread of Christianity in Poland. The impetus to the process was the Baptism of Poland (Polish: chrzest Polski [ˈxʂɛst ˈpɔl.ski]), the personal baptism of Mieszko I, the first ruler of the future Polish state, and much of his court. The ceremony took place on Holy Saturday, 14 April 966 (under the Julian pre-Gregorian calendar, equivalent to 19 April 966 Gregorian), although the exact location is disputed by historians, with the cities of Poznań and Gniezno being the most likely sites.
