The history of the Caucasus region may be divided into the history of the Northern Caucasus (Ciscaucasia), historically in the sphere of influence of Scythia and of Southern Russia (Eastern Europe), and that of the Southern Caucasus (Transcaucasia; Caucasian Albania, Georgia, Armenia), in the sphere of influence of Persia, Anatolia and for a very brief time Assyria.
Up to including the early 19th century, the Southern Caucasus and a part of the Northern Caucasus (Dagestan) all formed part of the Persian Empire. In 1813 and 1828 by the Treaty of Gulistan and the Treaty of Turkmenchay respectively, the Persians were forced to irrevocably cede the Southern Caucasus and Dagestan to Imperial Russia. Russia conquered and annexed the rest of the Northern Caucasus in the course of the 19th century in the Caucasian Wars (1817–1864).
The Northern Caucasus became the scene of intense fighting during the Second World War. Nazi Germany attempted to capture the Caucasus region from Soviet control in 1942 by a two-pronged attack towards both the western bank of the Volga (intending to seize the city of Stalingrad) and by a drive southeast towards Baku, a major center of oil production. The Nazis intended to establish a Reichskommissariat Kaukasus to control the Caucasian territories of the Soviet Union. Considerable parts of the northern Caucasus fell under German occupation, but the invasion eventually faltered as it failed to accomplish either goal, and Soviet soldiers drove the Germans back west following the Battle of Stalingrad (1942–1943).
