Georgian Soviet Socialist Republic

Georgia, formally the Georgian Soviet Socialist Republic, was one of the republics of the Soviet Union from its inception in 1922 to its breakup in 1991. Coterminous with the present-day republic of Georgia, it was based on the traditional territory of Georgia, which had existed as a series of independent states in the Caucasus prior to annexation by the Russian Empire in 1801. The Georgian SSR was formed in 1921 and subsequently incorporated in the Soviet Union in 1922. Until 1936 it was a part of the Transcaucasian Socialist Federative Soviet Republic, which existed as a union republic within the USSR. From November 18, 1989, the Georgian SSR declared its sovereignty over Soviet laws. The republic was renamed the Republic of Georgia on November 14, 1990, and subsequently became independent before the dissolution of the Soviet Union on April 9, 1991, whereupon each former SSR became a sovereign state.
Azerbaijan Soviet Socialist Republic

Azerbaijan, officially the Azerbaijan Soviet Socialist Republic, also referred to as Soviet Azerbaijan, was one of the constituent republics of the Soviet Union between 1922 and 1991. Created on 28 April 1920 when Soviet Russia brought pro-Soviet figures to power in the region, the first two years of the Azerbaijani SSR were as an independent country until incorporation into the Transcausasian SFSR, along with the Armenian SSR and the Georgian SSR.
Flag of Armenia

The national flag of Armenia, the Armenian Tricolour, consists of three horizontal bands of equal width, red on the top, blue in the middle, and orange on the bottom. The Armenian Supreme Soviet adopted the current flag on 24 August 1990. On 15 June 2006, the Law on the National Flag of Armenia, governing its usage, was passed by the National Assembly of Armenia.
Nakhichevan Autonomous Soviet Socialist Republic

The Nakhichevan Autonomous Soviet Socialist Republic, abbreviated as Nakhichevan ASSR, was an autonomous republic within the Azerbaijan SSR, itself a republic within the Soviet Union. It was formed on 16 March 1921 and became a part of the Azerbaijan SSR proper on 9 February 1924.
Flag of the Armenian Soviet Socialist Republic

The flag of the Armenian SSR was adopted on 17 December 1952 by the government of the Armenian SSR. The flag is similar to the flag of the Soviet Union but has a 1⁄4-width horizontal blue stripe in the middle. The red represents the "revolutionary struggle of the working masses" and the golden hammer and sickle represents the peasants' and workers' union.
Transcaucasian Democratic Federative Republic

The Transcaucasian Democratic Federative Republic, also known as the Transcaucasian Federation, was a short-lived South Caucasian state extending across what are now the modern-day countries of Armenia, Azerbaijan, and Georgia, plus parts of Eastern Turkey as well as Russian border areas.
Treaty of Kars

The Treaty of Kars was a peace treaty that established the common borders between Turkey and the three Transcaucasian republics of the Soviet Union. The treaty was signed in the city of Kars on 13 October 1921.
Mountainous Republic of the Northern Caucasus

The Mountainous Republic of the Northern Caucasus was a short-lived state situated in the Northern Caucasus that existed from 1917 until 1923. It broke away from the Russian Empire during the February Revolution, shortly before the start of the Russian Civil War.
Abkhaz Autonomous Soviet Socialist Republic

The Abkhaz Autonomous Soviet Socialist Republic, abbreviated as Abkhaz ASSR, was an autonomous republic of the Soviet Union within the Georgian SSR. It came into existence in February 1931, when the Socialist Soviet Republic of Abkhazia, originally created in March 1921, was transformed to the status of Autonomous Soviet Socialist Republic within the Georgian SSR.
Socialist Soviet Republic of Abkhazia

The Socialist Soviet Republic of Abkhazia was a short-lived republic within the Caucasus region of the Soviet Union that covered the territory of Abkhazia, and existed from 31 March 1921 to 19 February 1931. Formed in the aftermath of the Red Army invasion of Georgia in 1921, it was independent until 16 December 1921, when it agreed to a treaty uniting it with the Georgian Soviet Socialist Republic. The SSR Abkhazia was largely similar to an autonomous Soviet republic, though it retained de facto independence from Georgia, being given certain features only full union republics had, like its own military units. Through its status as a "treaty republic" with Georgia, Abkhazia joined the Transcaucasian Soviet Federative Socialist Republic, which united Armenian, Azerbaijani, and Georgian SSRs into one federal unit, when the latter was formed in 1922. The SSR Abkhazia was abolished in 1931 and replaced with the Abkhaz Autonomous Soviet Socialist Republic within the Georgian SSR.
History of the Caucasus

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, and that of the Southern Caucasus in the sphere of influence of Persia, Anatolia and for a very brief time Assyria.

The postage stamps and postal history of Azerbaijan describes the history of postage stamps and postal systems in Azerbaijan, which closely follows the political history of Azerbaijan, from its incorporation to the Russian Empire in 1806, to its briefly obtained independence in 1918, which it lost to the Soviet Union in 1920 and re-acquired it in 1991 after the fall of the Soviet Union.
Russian Soviet Federative Socialist Republic

The Russian Soviet Federative Socialist Republic, previously known as the Russian Soviet Republic and the Russian Socialist Federative Soviet Republic, as well as being unofficially known as the Russian Federation, Soviet Russia, or simply Russia, was an independent state from 1917 to 1922, and afterwards the largest, most populous and most economically developed of the 15 Soviet socialist republics of the Soviet Union (USSR) from 1922 to 1990, finally a sovereign part of the Soviet Union with priority of Russian laws over Union-level legislation in 1990 and 1991, the last two years of the existence of the USSR. The Russian Republic comprised sixteen smaller constituent units of autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais and forty oblasts. Russians formed the largest ethnic group. The capital of the Russian SFSR was Moscow and the other major urban centers included Leningrad, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara.
