Prior to the migration to the south, while still living in the Polabí region, Serbs may be among the first Slavic people who came in contact with Christianity. In the 7th century, they became part of the Merovingian kingdom, which not only had Christianity as an official religion but also had a concept of spreading the religion. Though records mention no Christianization attempts toward the Serbs specifically, there are writings regarding the, more or less successful missionary attempts among the Bavarians and Thuringians, the neighboring Germanic tribes which were conquered by the Franks in the 6th century.
