The beginning of the 20th century marked the first Armenian-Tartar clashes throughout Azerbaijan. This new phenomenon had two reasons. First, it was the result of increased tensions between the local Muslim population and Armenians, whose numbers increased throughout the 19th century as a result of Russian resettlement policies. Second, by the beginning of the 20th-century peoples of the Caucasus, similar to other non-Russian peoples in the periphery of the Russian Empire began to seek cultural and territorial autonomy. That is why, at the beginning of the 20th century in Russia itself was a period of bourgeois and Bolshevik revolutions, in the peripheries these movements have acquired a character of the national liberation movement.
