Democratic Republic of Georgia in the context of "Noe Zhordania"

The Apostolic Autocephalous Orthodox Church of Georgia (Georgian: საქართველოს სამოციქულო ავტოკეფალური მართლმადიდებელი ეკლესია, romanized: sakartvelos samotsikulo avt'ok'epaluri martlmadidebeli ek'lesia), commonly known as the Georgian Orthodox Church or the Orthodox Church of Georgia, is an autocephalous Eastern Orthodox church in full communion with the other churches of Eastern Orthodoxy. It is Georgia's dominant religious institution, and a majority of Georgian people are members. The Orthodox Church of Georgia is one of the oldest churches in the world. It asserts apostolic foundation, and that its historical roots can be traced to the early and late Christianization of Iberia and Colchis by Andrew the Apostle in the 1st century AD and by Saint Nino in the 4th century AD, respectively. As in similar autocephalous Eastern Orthodox Christian churches, the church's highest governing body is the holy synod of bishops. The church is headed by the Patriarch of All Georgia, Ilia II, who was elected in 1977.

Eastern Orthodox Christianity was the state religion throughout most of Georgia's history until 1921, when the country, having declared independence from Russia in 1918, was occupied by the Red Army during the Soviet invasion of Georgia, becoming part of the Soviet Union. The current Constitution of Georgia recognizes the special role of the Georgian Orthodox Church in the country's history, but also stipulates the independence of the church from the state. Government relations are further defined and regulated by the Concordat of 2002.

The First Republic of Armenia, officially known at the time of its existence as the Republic of Armenia, was an independent Armenian state that existed from May (28th de jure, 30th de facto) 1918 to 2 December 1920 in the Armenian-populated territories of the former Russian Empire known as Eastern or Russian Armenia. The republic was established in May 1918, with its capital in the city of Yerevan, after the dissolution of the short-lived Transcaucasian Federation. It was the first Armenian state since the Middle Ages.

In its first year of independence, Armenia was confined to a small territory around Lake Sevan after its invasion by the Ottoman Empire during the Caucasus campaign. Following the Armistice of Mudros, Armenia expanded its borders in the wake of the Ottoman withdrawal, leading to a brief border war with neighbouring Georgia. During its first winter, hundreds of thousands of refugees in the country who had fled the Armenian genocide died from starvation or exposure. In the spring of 1919, Armenia, with British support, incorporated the formerly occupied regions of Kars and Nakhchivan, thereby tripling in size since independence; however, Armenian control of these regions collapsed during the Muslim uprisings that erupted in the summer of 1919.

The Soviet invasion of Georgia (12 February – 17 March 1921), also known as the Georgian–Soviet War or the Red Army invasion of Georgia, was a military campaign by the Russian Soviet Red Army aimed at overthrowing the Social Democratic (Menshevik) government of the Democratic Republic of Georgia (DRG) and installing a Bolshevik regime (Communist Party of Georgia) in the country. The conflict was a result of expansionist policy by the Russians, who aimed to control as much as possible of the lands which had been part of the former Russian Empire until the turbulent events of the First World War, as well as the revolutionary efforts of mostly Russian-based Georgian Bolsheviks, who did not have sufficient support in their native country to seize power without external intervention.

The independence of Georgia had been recognized by Russia in the Treaty of Moscow, signed on 7 May 1920, and the subsequent invasion of the country was not universally agreed upon in Moscow. It was largely engineered by two influential Georgian-born Soviet officials, Joseph Stalin and Sergo Ordzhonikidze, who on 14 February 1921 received the consent of Russian leader Vladimir Lenin to advance into Georgia, on the pretext of supporting the alleged "peasants' and workers' rebellion" in the country. Russian forces took the Georgian capital Tbilisi (then known as Tiflis to most non-Georgian speakers) after heavy fighting and declared the Georgian Soviet Socialist Republic on 25 February 1921. The rest of the country was overrun within three weeks, but it was not until September 1924 that Soviet rule was firmly established. Almost simultaneous occupation of a large portion of southwest Georgia by Turkey (February–March 1921) threatened to develop into a crisis between Moscow and Ankara, and led to significant territorial concessions by the Soviets to the Turkish National Government in the Treaty of Kars.

The Caucasus campaign comprised armed conflicts between the Russian Empire and the Ottoman Empire, later including Armenia, Azerbaijan, Georgia, the Mountainous Republic of the Northern Caucasus, the German Empire, the Central Caspian Dictatorship, and the British Empire, as part of the Middle Eastern theatre during World War I. The Caucasus campaign extended from the South Caucasus to the Armenian Highlands region, reaching as far as Trabzon, Bitlis, Mush and Van. The land warfare was accompanied by naval engagements in the Black Sea.

The Russian military campaign started on 1 November 1914 with the Russian invasion of Turkish Armenia. In February 1917, the Russian advance was halted following the Russian Revolution. The Russian Caucasus Army soon disintegrated and was replaced by the forces of the newly established Transcaucasian state, comprising partly of Armenian volunteer units and irregular units which had previously been part of the Russian Army. During 1918 the region also saw the establishment of the Central Caspian Dictatorship, the Republic of Mountainous Armenia and an Allied intervention force, nicknamed Dunsterforce, composed of troops drawn from the Mesopotamian and Western Fronts.

The Azerbaijan Democratic Republic (Azerbaijani: Azərbaycan Demokratik Cümhuriyyəti), also known as the Azerbaijan People's Republic (Azerbaijani: Azərbaycan Xalq Cümhuriyyəti; آذربایجان خلق جمهوریتی‎), was the first secular democratic republic in the Turkic and Muslim worlds. The ADR was founded by the Azerbaijani National Council in Tiflis on 28 May 1918 after the collapse of the Transcaucasian Democratic Federative Republic, and ceased to exist on 28 April 1920. Its established borders were with Russia to the north, the Democratic Republic of Georgia to the north-west, the Republic of Armenia to the west, and Iran to the south. It had a population of around 3 million. Ganja was the temporary capital of the Republic as Baku was under Bolshevik control.

Under the ADR, a government system was developed in which a Parliament elected on the basis of universal, free, and proportionate representation was the supreme organ of state authority; the Council of Ministers was held responsible before it. Fatali Khan Khoyski became its first prime minister. Besides the Musavat majority, Ahrar, Ittihad, Muslim Social Democrats as well as representatives of Armenian (21 out of 120 seats), Russian, Polish, German, and Jewish minorities gained seats in the parliament. Many members supported Pan-Islamist and Pan-Turkist ideas.

Tao-Klarjeti (Georgian: ტაო-კლარჯეთი, romanized: t'ao-k'larjeti [tʼäo̞kʼɫäɾd͡ʒe̞t̪ʰi]) is a Georgian historical and cultural region in north-eastern Turkey. The region is based around two river basins - Chorokhi and Kura (Mtkvari), and also partially includes the upper source of the Aras river. In modern usage it most often denotes the territory that was administered or claimed by Georgian Democratic Republic but is nowadays part of Turkey due to the Soviet-Turkish deal in 1921.

The term "Tao-Klarjeti" is based on the names of two most important provinces of the region — Tao and Klarjeti. The term is equivalent to “Zemo Kartli” (i.e., Upper Kartli or Upper Iberia) and is also a synonym for historical Meskheti.

The Armeno-Georgian War was a short border dispute that was fought in December 1918 between the newly independent Democratic Republic of Georgia and the First Republic of Armenia, largely over the control of former districts of the Tiflis Governorate, in Borchaly (Lori) and Akhalkalaki.

In May 1918, towards the end of World War I, Armenia and Georgia both declared their independence, dissolving the short-lived union between them. Both Georgia and Armenia claimed Lori and Akhalkalaki, both of which were populated primarily by Armenians. The border dispute turned into an open military conflict on 7 December 1918. Armenian forces initiated coup de mains that brought them within 10 kilometers of the Georgian capital, Tiflis, before Georgian troops were able to organize counterattacks. Allied intervention forced a ceasefire. Battles continued until the ceasefire came into effect at midnight on December 31.
