South Caucasus

Transcaucasia (Russian: Закавказье), or the South Caucasus, is a geopolitical region in the vicinity of the southern Caucasus Mountains on the border of Eastern Europe and Western Asia. Transcaucasia roughly corresponds to modern Georgia, Armenia, and Azerbaijan. Transcaucasia and Ciscaucasia (North Caucasus) together comprise the larger Caucasus geographical region that divides Eurasia.

Transcaucasia spans the southern portion of the Caucasus Mountains and their lowlands, straddling the border between the continents of Europe and Asia, and extending southwards from the southern part of the Greater Caucasus mountain range of southwestern Russia to the Turkish and Armenian borders, and from the Black Sea in the west to the Caspian Sea coast of Iran in the east. The area includes the southern part of the Greater Caucasus mountain range, the entire Lesser Caucasus mountain range, the Colchis Lowlands, the Kura-Aras Lowlands, the Talysh Mountains, the Lenkoran Lowlands, Javakheti and the eastern portion of the Armenian Highland.
