The Russian conquest of the Caucasus mainly occurred between 1800 and 1864. In that era the Russian Empire expanded to control the region between the Black Sea and Caspian Sea, the territory that is modern Armenia, Azerbaijan, Georgia, and parts of Iran and Turkey, as well as the North Caucasus region of modern Russia. Multiple wars were fought against the local rulers of the regions, as well as the dominant powers, the Ottoman Empire and Persian Empire, for control. By 1864 the last regions were brought under Russian control.
