Uzbekistan, officially also the Republic of Uzbekistan, is a doubly landlocked Central Asian Sovereign state. It 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. The first recorded settlers were Eastern Iranian nomads, known as Scythians, who founded kingdoms in Khwarezm, Bactria, Sogdia, Fergana, and Margiana. The area was incorporated into the Persian Empire and, after a period of Macedonian Greek rule, was ruled mostly by Persian dynasties until the Muslim conquest in the 7th century, turning the majority of the population towards 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.
