Information:  - Russian ("", pronounced ) is an East Slavic language and an official language in Russia, Belarus, Kazakhstan, Kyrgyzstan and many minor or unrecognised territories. It is an unofficial but widely spoken language in Ukraine and Latvia, and to a lesser extent, the other countries that were once constituent republics of the Soviet Union and former participants of the Eastern Bloc. Russian belongs to the family of Indo-European languages and is one of the four living members of the East Slavic languages. Written examples of Old East Slavonic are attested from the 10th century and beyond.  - Belarusians ("bielarusy"), or Byelorussians, are an East Slavic ethnic group who are native to modern-day Belarus and the immediate region. There are over 9.5 million people who proclaim Belarusian ethnicity worldwide, with overwhelming majority residing either in Belarus or the adjacent countries where they are an autochthonous minority.  - The Tatars are a Turkic people living in Asia and Europe who were one of the five major tribal confederations ("khanlig") in the Mongolian plateau in the 12th century CE. The name "Tatar" first appears in written form on the Kul Tigin monument as  ("TaTaR"). Historically, the term "Tatars" was applied to a variety of Turco-Mongol semi-nomadic empires who controlled the vast region known as Tartary. More recently, however, the term refers more narrowly to people who speak one of the Turkic languages.  - Russians ("russkiye") are an East Slavic ethnic group native to Eastern Europe. The majority of Russians inhabit the nation state of Russia, while notable minorities exist in Ukraine, Kazakhstan, and other former Soviet states such as Belarus.
