Uzbekistan (,, Ўзбекистон/Oʻzbekistonofficially also the Republic of Uzbekistan (Oʻzbekiston Respublikasi), is a landlocked country—the only doubly landlocked one (i.e. surrounded solely by other landlocked countries)—in Central Asia and one of only two anywhere in the world (the other being Liechtenstein). The sovereign state is a secular, unitary constitutional republic, comprising 12 provinces, one autonomous republic, and a capital city. Uzbekistan is bordered by five landlocked countries: Kazakhstan to the north; Kyrgyzstan to the northeast; Tajikistan to the southeast; Afghanistan to the south; and Turkmenistan to the southwest.
What is now Uzbekistan was in ancient times part of the Iranian-speaking region of Transoxiana and Turan. The first recorded settlers were Eastern Iranian nomads, known as Scythians, who founded kingdoms in Khwarezm (8th–6th centuries BC), Bactria (8th–6th centuries BC), Sogdia (8th–6th centuries BC), Fergana (3rd century BC – 6th century AD), and Margiana (3rd century BC – 6th century AD). The area was incorporated into the Persian Empire and, after a period of Macedonian Greek rule, was ruled mostly by Persian dynasties. The Muslim conquest in the 7th century converted the majority of the population, including the local ruling classes, into adherents of Islam. During this period, cities such as Samarkand, Khiva and Bukhara began to grow rich from the Silk Road. The local Khwarezmian dynasty, and Central Asia as a whole, were decimated by the Mongol invasion in the 13th century. After the Mongol Conquests, the area became increasingly dominated by Turkic peoples. The city of Shahrisabz was the birthplace of the Turco-Mongol warlord Timur, also known as one of Genghis Khan's grandchildren, who in the 14th century established the Timurid Empire and was proclaimed the Supreme Emir of Turan with his capital in Samarkand. The area was conquered by Uzbek Shaybanids in the 16th century, moving the centre of power from Samarkand to Bukhara. The region was split into three states: Khanate of Khiva, Khanate of Kokand, and Emirate of Bukhara. It was gradually incorporated into the Russian Empire during the 19th century, with Tashkent becoming the political center of Russian Turkestan. In 1924, after national delimitation, the constituent republic of the Soviet Union known as the Uzbek Soviet Socialist Republic was created. Following the breakup of the Soviet Union, it declared independence as the Republic of Uzbekistan on 31 August 1991.
