Historically, Dagestan (Caucasian Albania) consisted of a federation of mountainous principalities in the eastern part of the North Caucasus. Located at the crossroads of world civilizations of north and south, Dagestan was the scene of clashes of interests of many states and until the early 19th century most notably that of between Persia (Iran) and Imperial Russia.
The name Dagestan historically refers to the eastern Caucasus, in 1860 taken by the Russian Empire and renamed the Dagestan Oblast. The current, more autonomous Republic of Dagestan covers a much larger territory, established in 1921 as the Dagestan Autonomous Soviet Socialist Republic, by inclusion of the eastern part of Terek Oblast.
