The impact of the mission of Cyril and Methodius extended beyond the religious and political spheres. Old Church Slavonic became the fourth liturgical language of the Christian world. However, after Methodius's death (885) all his followers were expelled from Great Moravia; accordingly, the use of Slavic liturgy in Great Moravia lasted only about 22 years. Its late form remains the liturgical language of the Ukrainian, Russian, Bulgarian, Macedonian, Serbian and Polish Orthodox Churches. Cyril also invented the Glagolitic alphabet, suitable for Slavic languages, and first translated the Bible into a Slavic language, along with Methodius, who later completed the project.
