the early cyrillic alphabet is a writing system that was developed in the first bulgarian empire during the late 9th century on the basis of the greek alphabet for the slavic peoples living near the byzantine empire in south east and central europe. the objective was to make it possible to have christian service in slavic tongue, instead of in greek, which locals did not understand, and to bring bulgarian subjects closer to the cultural influence of christianity, the official religion of the byzantine empire. it was used by slavic peoples in south east, central and eastern europe.
it was developed in the preslav literary school in the capital city of the first bulgarian empire in order to write the old church slavonic language (called also old bulgarian). the modern cyrillic script is still used primarily for some slavic languages (such as bulgarian, serbian, russian and ukrainian), and for east european and asian languages that have experienced a great amount of russian cultural influence.
among some of the traditionally culturally influential countries using cyrillic script are bulgaria, russia, serbia and ukraine.
