Christianization of Poland

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.
