(See Russian conquest of the Caucasus). Sukhumi was declared the seaport in 1847 and was directly annexed to the Russian Empire after the ruling Shervashidze princely dynasty was ousted by the Russian authorities in 1864. During the Russo-Turkish War, 1877–1878, the town was temporarily controlled by the Ottoman forces and Abkhaz-Adyghe rebels. After its annexation, Sukhumi became the administrative center of the Sukhumi Okrug of the Kutais Governorate.
