Rastislav, great king of Moravia, was interested in finding priests who could preach to his people in their own language, so he contacted the church in Constantinople. Methodius and Constantine, two brothers of Slavic origin were sent. The brothers were pivotal in the spread of Christianity into Eastern Europe. They also translated the Bible and invented the Cyrillic alphabet. This decision to preach to people in their local language contributed enormously to the popularity and success of the Orthodox Church.
