A region between the Black and Caspian seas that includes southwest Russia, Georgia, Azerbaijan, and Armenia, and that forms part of the traditional boundary between Europe and Asia. Inhabited before 2000 B.C., it was the scene of countless invasions over the millennia. Conquered by Russia during the 18th and 19th centuries, the region has vast oil resources, which were a major German objective in World War II. Following the collapse of the USSR in 1991, the region became the site of various secessionist movements.
