Most Bashkirs speak the Bashkir language, which is similar to the Tatar, Kazakh and Kyrgyz languages.The Bashkir language belongs to the Kipchak branch of Turkic languages; they share historical and cultural affinities with the broader Turkic peoples. Bashkirs are mainly Sunni Muslims of the Hanafi schoolmadhhab, or school of jurisprudence, and follow the Jadid doctrine. Previously nomadic and fiercely independent, the Bashkirs gradually came under Russian rule beginning in the 16th century; they have since played a major role through the history of Russia, culminating in their autonomous status within the Russian Empire, Soviet Union and post-Soviet Russia.
