The Nakhchivan Autonomous Republic (Azerbaijani: Naxçıvan Muxtar Respublikası, pronounced [nɑxtʃɯˈvɑn muxˈtɑɾ ɾesˈpublikɑsɯ]) is a landlocked exclave of the Republic of Azerbaijan. The region covers 5,502.75 km (2,124.62 sq mi) with a population of 459,600. It is bordered by Armenia to the east and north, Iran to the southwest, and Turkey to the west. It is the sole autonomous republic of Azerbaijan, governed by its own elected legislature.
The republic, especially the capital city of Nakhchivan, has a long history dating back to about 1500 BC. Nakhijevan was one the cantons of the historical Armenian province of Vaspurakan in the Kingdom of Armenia. Historically, the Persians, Armenians, Mongols, and Turks all competed for the region. The area that is now Nakhchivan became part of Safavid Iran in the 16th century. The semi-autonomous Nakhchivan Khanate was established there in the mid-18th century. In 1828, after the last Russo-Persian War and the Treaty of Turkmenchay, the Nakhchivan Khanate passed from Iranian into Imperial Russian possession.
