Christianization of Poland

The Christianization of Poland occurred around 966 AD when Duke Mieszko I adopted Christianity, mainly to strengthen political alliances and unify his territory. This process involved the conversion of the ruling elite, the establishment of Christian institutions like churches and monasteries, and the integration of Christian practices into local culture. It marked Poland’s official entry into European Christendom, shaping its religious, cultural, and political identity. Over time, Christianity became deeply rooted, influencing Polish laws, education, art, and society, and helping to forge a unified national identity.
