Transcaucasia is a geographical area that includes Armenia, Azerbaijan and Georgia. In the past it has been also a political entity during the ephemeral Federal Democratic Republic of Transcaucasia (February-May 1918) and the Soviet Federative Socialist Republic of Transcaucasia (1922-1936).
After having been under the influence of Persian, Ottoman and Russian empires; the modern history of Transcaucasia is marked by the Soviet yoke imposed throughout the twentieth century. This period ended with bloody wars of independence that saw the birth of three recognized States (Armenia, Azerbaijan and Georgia), three unrecognized States (Abkhazia, South Ossetia and Nagorno-Karabakh) and a lot of autonomous claims.
