Armenian Soviet Socialist Republic in the context of "Hawar alphabet"

Yerevan (UK: /ˌjɛrəˈvæn/ YERR-ə-VAN, US: /-ˈvɑːn/, -⁠VAHN; Armenian: Երևան [jɛɾɛˈvɑn] ; sometimes spelled Erevan) is the capital and largest city of Armenia, as well as one of the world's oldest continuously inhabited cities. Situated along the Hrazdan River, Yerevan is the administrative, cultural, and industrial centre of the country, as its primate city. It has been the capital since 1918, the fourteenth in the history of Armenia and the seventh located in or around the Ararat Plain. The city also serves as the seat of the Araratian Pontifical Diocese, which is the largest diocese of the Armenian Apostolic Church and one of the oldest dioceses in the world.

The history of Yerevan dates back to the 8th century BC, with the founding of the fortress of Erebuni in 782 BC by King Argishti I of Urartu at the western extreme of the Ararat Plain. Erebuni was "designed as a great administrative and religious centre, a fully royal capital." By the late ancient Armenian Kingdom, new capital cities were established and Yerevan declined in importance. The city was mostly depopulated by the Great Surgun of 1603–05, when the Safavid Empire forcibly deported hundreds of thousands of Armenians to Iran. In 1679, the city was mostly destroyed by an earthquake, and then rebuilt on a smaller scale. In 1828, Yerevan became part of the Russian Empire, which led to the repatriation of Armenians whose ancestors had been forcibly relocated in the 17th century. After World War I, Yerevan became the capital of the First Republic of Armenia as thousands of survivors of the Armenian genocide in the Ottoman Empire arrived in the area. The city expanded rapidly during the 20th century while Armenia was a part of the Soviet Union. In a few decades, Yerevan was transformed from a provincial town within the Russian Empire to Armenia's principal cultural, artistic, and industrial centre, as well as becoming the seat of national government.

The post-Soviet states, also referred to as the former Soviet Union or the former Soviet republics, are the independent sovereign states that emerged/re-emerged from the dissolution of the Soviet Union in 1991. Prior to their independence, they existed as Union Republics, which were the top-level constituents of the Soviet Union. There are 15 post-Soviet states in total: Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan. Each of these countries succeeded their respective Union Republics: the Armenian SSR, the Azerbaijan SSR, the Byelorussian SSR, the Estonian SSR, the Georgian SSR, the Kazakh SSR, the Kirghiz SSR, the Latvian SSR, the Lithuanian SSR, the Moldavian SSR, the Russian SFSR, the Tajik SSR, the Turkmen SSR, the Ukrainian SSR, and the Uzbek SSR. In Russia, the term "near abroad" (Russian: ближнее зарубежье, romanized: bližneye zarubežye) is sometimes used to refer to the post-Soviet states other than Russia.

Following the transition period and cessation of the existence of the Soviet Union, post-Soviet states and the international community de facto and de jure recognized Russia as the only continuator state to the Soviet Union as a whole, rather than to just the Russian SFSR including UN and UNSC membership (see agreements in Succession, continuity and legacy of the Soviet Union). The other post-Soviet states were recognized as successors only to their corresponding Union Republics and to international treaties concluded by the Soviet Union. All 12 post-Soviet states are successors of the Soviet Union, but not continuators.

The Transcaucasian Socialist Federative Soviet Republic (Transcaucasian SFSR or TSFSR), also known as the Transcaucasian Soviet Federative Socialist Republic, or simply Transcaucasia, was a republic of the Soviet Union that existed from 1922 to 1936.

The TSFSR comprised Armenia, Azerbaijan, and Georgia, traditionally known as the "Transcaucasian Republics" as they were separated from Russia by the Caucasus Mountains. It was created in March 1922 to unify the region following a Soviet invasion two years prior, and was one of the four republics to sign the Treaty on the Creation of the Union of Soviet Socialist Republics establishing the Soviet Union in December 1922. The TSFSR was dissolved upon the adoption of the 1936 Soviet Constitution and its constituent republics were elevated individually to republics of the Soviet Union.

The Georgian Soviet Socialist Republic, also known as Soviet Georgia, the Georgian SSR, or simply Georgia, was one of the republics of the Soviet Union from its second occupation (by the Red Army) in 1921 to its independence in 1991. Coterminous with the present-day republic of Georgia as well as the contested regions of Abkhazia and South Ossetia, it was based on the traditional territory of Georgia, which had existed as a series of independent states in the Caucasus prior to the first occupation of annexation in the course of the 19th century. 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.

Geographically, the Georgian SSR was bordered by Turkey to the south-west and the Black Sea to the west. Within the Soviet Union it bordered the Russian SFSR to the north, the Armenian SSR to the south and the Azerbaijan SSR to the south-east.

In September 1920, remnants of the Ottoman Army's XV Corps under the command of Kâzım Karabekir attacked the First Republic of Armenia, specifically in the Kars. Karabekir had orders from the Ankara Government to "eliminate Armenia physically and politically". One estimate places the number of Armenians massacred by the Turkish army during the invasion at 100,000—this is evident in the marked decline (−25.1%) of the population of modern-day Armenia from 961,677 in 1919 to 720,000 in 1920. The Turkish military victory was followed by the Red Army invasion of Armenia and the establishment of the Armenian Soviet Socialist Republic. The Turkish invasion and occupation had drastic humanitarian impacts to Armenia's population, triggering condemnation from German and USA officials. According to several historians, only Soviet intervention prevented the completion of the Armenian genocide.

The hostilities ended with the Treaty of Alexandropol and the effective partition of Armenia between Kemalist Turkey and the Soviet union: most of Western Armenia was transferred to Turkey and Eastern Armenia was incorporated into the Soviet Union as the Armenian Socialist Republic. This status was solidified by the annulment of the Treaty of Sevres, and the ratification of the Treaty of Moscow (March 1921) and Treaty of Kars (October 1921) between Soviet Russia and the Grand National Assembly of Turkey.

The Treaty of Kars was a treaty that established the borders between Turkey and the three Transcaucasian Soviet republics, which are now the independent republics of Armenia, Georgia and Azerbaijan. The treaty was signed in the city of Kars on 13 October 1921.

Signatories of the Treaty of Kars included representatives from the Grand National Assembly of Turkey, which would declare the Republic of Turkey in 1923, and from the Armenian, Azerbaijani and Georgian Socialist Soviet Republics with the participation of the Russian Soviet Federative Socialist Republic. The last four parties would become constituent parts of the Soviet Union after the victory of the Bolsheviks in the Russian Civil War and the December 1922 Union Treaty.
