Yerevan (Armenian: Երևան, Armenian pronunciation: [jɛɾɛˈvɑn]) is the capital and largest city of Armenia and one of the world's oldest continuously-inhabited cities. Situated along the Hrazdan River, Yerevan is the administrative, cultural, and industrial center of the country. It has been the capital since 1918, the thirteenth in the history of Armenia.

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 at the western extreme of the Ararat plain. After World War I, Yerevan became the capital of the Democratic Republic of Armenia as thousands of survivors of the Armenian Genocide settled in the area. The city expanded rapidly during the 20th century as Armenia became one of the fifteen republics in the Soviet Union. In fifty years, Yerevan was transformed from a town of a few thousand residents within the Russian Empire, to Armenia's principal cultural, artistic, and industrial center, as well as becoming the seat of national government.

Armenia ⁱ/ɑrˈmiːniə/ (Armenian: Հայաստան Hayastan [hɑjɑsˈtɑn]), officially the Republic of Armenia (Հայաստանի Հանրապետություն, Hayastani Hanrapetut’yun, [hɑjɑstɑˈni hɑnɾɑpɛtuˈtʰjun]), is a landlocked, mountainous country in the South Caucasus region of Eurasia. Located at the crossroads of Western Asia and Eastern Europe, it is bordered by Turkey to the west, Georgia to the north, the de facto independent Nagorno-Karabakh Republic and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south.

A former republic of the Soviet Union, Armenia is a unitary, multiparty, democratic nation-state with an ancient and historic cultural heritage. The Kingdom of Armenia became the first state in the world to adopt Christianity as its religion, in the early years of the 4th century (the traditional date is 301 AD). The modern Republic of Armenia recognizes the Armenian Apostolic Church, the world's oldest national church, as the country's primary religious establishment. Armenians have their own unique alphabet invented by Mesrob Mashtots in 406 AD.
