Flag of the Republic of Armenia

Armenia, officially the Republic of Armenia, is a landlocked country in the Armenian highlands of West Asia. It is a part of the Caucasus region and is bordered by Turkey to the west, Georgia to the north and Azerbaijan to the east, and Iran and the Azerbaijani exclave Nakhchivan to the south. Yerevan is the capital, largest city and financial centre. The Armenian highlands have been home to the Hayasa-Azzi, Shupria and Nairi peoples. By at least 600 BC, an archaic form of Proto-Armenian, an Indo-European language, had diffused into the Armenian highlands. The first Armenian state of Urartu was established in 860 BC, and by the 6th century BC it was replaced by the Satrapy of Armenia. The Kingdom of Armenia reached its height under Tigranes the Great in the 1st century BC and in AD 301 became the first state in the world to adopt Christianity as its official religion. Armenia still recognises the Armenian Apostolic Church, the world's oldest national church, as the country's primary religious establishment. The ancient Armenian kingdom was split between the Byzantine and Sasanian Empires around the early 5th century. Under the Bagratuni dynasty, the Bagratid Kingdom of Armenia was restored in the 9th century before falling in 1045. Cilician Armenia, an Armenian principality and later a kingdom, was located on the coast of the Mediterranean Sea between the 11th and 14th centuries. Between the 16th and 19th centuries, the traditional Armenian homeland composed of Eastern Armenia and Western Armenia came under the rule of the Ottoman and Persian empires, repeatedly ruled by either of the two over the centuries. By the 19th century, Eastern Armenia had been conquered by the Russian Empire while most of Western Armenia remained under Ottoman rule. During World War I up to 1.5 million Armenians were systematically exterminated in the Armenian genocide. In 1918, following the Russian Revolution, all non-Russian countries declared their independence after the Russian Empire ceased to exist, leading to the establishment of the First Republic of Armenia. By 1920, the state was incorporated into the Soviet Union as the Armenian Soviet Socialist Republic. Today's Republic of Armenia became independent in 1991 during the dissolution of the Soviet Union. Modern Armenia is a unitary, multi-party, democratic nation-state. It is a developing country and ranks 69th on the Human Development Index as of 2023. Its economy is primarily based on industrial output and mineral extraction. While Armenia is geographically located in the South Caucasus, Armenia views itself as part of Europe and is generally considered geopolitically European. The country is a member of numerous European organisations including the Organisation for Security and Co-Operation in Europe, the Council of Europe, the Eastern Partnership, Eurocontrol, the Assembly of European Regions, and the European Bank for Reconstruction and Development. Armenia is a member of certain regional groups throughout Eurasia, including the Asian Development Bank, the Collective Security Treaty Organisation, the Eurasian Economic Union, and the Eurasian Development Bank. Armenia supported the once de facto independent Republic of Artsakh (Nagorno-Karabakh), which had seceded from Azerbaijan in 1991, until Azerbaijan reincorporated the region through a siege and military offensive in 2023.
