Turkmenistan formerly also known as Turkmenia, is one of the Turkic states in Central Asia. Turkmenistan is bordered by Afghanistan to the southeast, Iran to the south and southwest, Uzbekistan to the east and northeast, Kazakhstan to the northwest and the Caspian Sea to the west.
Present-day Turkmenistan covers territory that has been at the crossroads of civilizations for centuries. In medieval times Merv (today known as Mary) was one of the great cities of the Islamic world, and an important stop on the Silk Road, a large road used for trade with China until the mid-15th century. Annexed by the Russian Empire in 1881, Turkmenistan later figured prominently in the anti-Bolshevik movement in Central Asia. In 1924, Turkmenistan became a constituent republic of the Soviet Union, Turkmen Soviet Socialist Republic (Turkmen SSR); it became independent upon the dissolution of the Soviet Union in 1991.
