The Caucasian War or the Caucasus War was a 19th-century military conflict between the Russian Empire and various peoples of the North Caucasus who resisted subjugation during the Russian conquest of the Caucasus. It consisted of a series of military actions waged by the Russian Imperial Army and Cossack settlers against the native inhabitants such as the Adyghe, Abaza-Abkhazians, Ubykhs, Chechens, and Dagestanis as the Tsars sought to expand.

The Principality of Abkhazia, emerged as a separate feudal entity in the 15th-16th centuries, amid the civil wars in the Kingdom of Georgia that concluded with the dissolution of the unified Georgian monarchy. The principality retained a degree of autonomy under Ottoman and then Russian rule, but was eventually absorbed into the Russian Empire in 1864.
