Like the various ethnic groups in Russia, many of them also have a unique language, many of which are either a Turkic language (related to many languages in Central Asia and in Turkey or a Uralic language (related to Hungarian, Finnish, and other minor languages in Scandinavia and Russia). Russian is the most commonly spoken language and nearly everyone learns Russian as the main means of communication between ethnic groups. English and other popular international languages have only recently begun being taught in mass numbers, but many young people have at least a working understanding of English today.
Religion
There is no official religion in Russia and, partially due to the intentional destruction of religion during time spans under the communists, the country is primarily atheist or does not adhere to a specific faith. The most popular religion is Russian Orthodox, but less than a quarter of the people actually adheres to this religion. There is also a significant Muslim population as many of the minority groups are, generally speaking, Muslim, although many others have converted to Orthodoxy or abandoned an attachment to any particular religion. Most people will claim to be religious or a believer of a Higher Being, but do not practice a particular religion nor do they prescribe to any individual faith.
Orthodoxy is a Christian religion that claims to be the most loyal to the Christian faith and religion as it was described by Jesus and the Gospels in the New Testament. Christianity, including Orthodoxy, was founded after the death of Jesus in about 30-33 AD; various branches of Orthodoxy were officially recognized by governments long before Catholicism was recognized in the Roman Empire.
