These Slavic people consisted of Polish and Bohemian kingdoms. These Slavs were converted by the German kings because the kings felt an obligation to tell them. At the end of the 9th century, there were many of the Czechs who were converted, and in the 10th century, there was a bishop of Prague. When Prince Mieszko was ruler, the Polish Slavs became converted. The pope later established an archbishop in Gniezno. The Hungarians were also later converted by German kings. This was made possible by Saint Stephen, who was Hungary's king around the 11th century. Because of these conversions, many of the Western Slavs were now Christians.
