Armenia (ⁱ/ɑːrˈmiːniə/, /-ˈmiːnjə/;Armenian: Հայաստան, tr. Hayastan, IPA: [hɑjɑsˈtɑn]), officially the Republic of Armenia (Armenian: Հայաստանի Հանրապետություն, tr. Hayastani Hanrapetut’yun), is a sovereign state in the South Caucasus region of Eurasia. Located in Western Asia, 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.

Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. The Kingdom of Van was established in 860 BC and by the 6th century BC it was replaced by the Satrapy of Armenia. In the 1st century BC the Kingdom of Armenia reached its height under Tigranes the Great. Armenia became the first state in the world to adopt Christianity as its official religion. In between the late 3rd century to early years of the 4th century, the state became "the first Christian nation." The official date of state adoption of Christianity was 301 AD. The ancient Armenian kingdom was split between the Byzantine and Sasanid empires around the early 5th century. Under the Bagratuni dynasty, the Armenian Kingdom was restored in the 9th century. Declining due to the wars against the Byzantines, the kingdom fell in 1045 and Armenia was soon after invaded by the Seljuk Turks. An Armenian principality and later a kingdom Cilician Armenia was located on the coast of the Mediterranean Sea between the 11th and 14th centuries.

With 78.4 million inhabitants, Iran is the world's 17th-most-populous country. It is the only country that has both a Caspian Sea and an Indian Ocean coastline. Iran has long been of geostrategic importance because of its central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz.

Azerbaijan

Azerbaijan (ⁱ/ˌæzərbaɪˈdʒɑːn/ AZ-ər-by-JAHN; Azerbaijani: Azərbaycan [ɑzærbɑjdʒɑn]), officially the Republic of Azerbaijan (Azerbaijani: Azərbaycan Respublikası), is a transcontinental country in the Caucasus region, situated at the crossroads of Eastern Europe and Western Asia. It is bounded by the Caspian Sea to the east, Russia to the north, Georgia to the northwest, Armenia to the west and Iran to the south. The exclave of Nakhchivan is bounded by Armenia to the north and east, Iran to the south and west, while having a short border with Turkey in the northwest.

The Azerbaijan Democratic Republic proclaimed its independence in 1918 and became the first Muslim-majority democratic and secular republic. It was also the first Muslim-majority country to have operas, theaters and modern universities. The country was incorporated into the Soviet Union in 1920 as the Azerbaijan Soviet Socialist Republic. Azerbaijan proclaimed its independence on 30 August 1991, before the official dissolution of the USSR. In September 1991, the disputed Armenian-majority Nagorno-Karabakh region re-affirmed its willingness to create a separate state as the Nagorno-Karabakh Republic. The region, effectively independent since the beginning of the Nagorno-Karabakh War in 1991, is internationally recognized as part of Azerbaijan until a final solution to its status is found through negotiations facilitated by the OSCE.
