paragraph_text: The region of modern Eastern Europe and Central Eurasia (Russia, Ukraine and other countries of the ex-USSR) have a long history of Christianity and Christian communities on its lands. In ancient times, in the first centuries after the birth of Christ, when this region was called[by whom?] Scythia - Christians already lived there. Later the region saw the first states to adopt Christianity officially - initially in Armenia (301 AD) and in Georgia (337 AD), later in the Great Russian Principality (Kyivan Rus, Russian: Великое княжество Русское, ca 988 AD). People of that time used to denote themselves Christians (христиане, крестьяне) and Russians (русские). Both terms had strong Christian connotations.[citation needed] It is also interesting that in time the term "крестьяне" acquired the meaning "peasants of Christian faith" and later "peasants" (the main part of the population of the region), while the term "христиане" retained its religious meaning and the term "русские" began to mean representatives of the heterogeneous Russian nation formed on the basis of common Christian faith and language,[citation needed] which strongly influenced the history and development of the region. In the region the "Pravoslav faith" (православная вера - Orthodox faith) or "Russian faith" (русская вера) from earliest times became almost as known as the original "Christian faith" (христианская, крестьянская вера). Also in some contexts the term "cossack" (козак, казак - free man by the will of God) was used[by whom?] to denote "free" Christians of steppe origin and Russian language.
