Uzbekistan is situated in central Asia between the Amu Darya and Syr Darya Rivers, the Aral Sea, and the slopes of the Tien Shan Mountains. It is bounded by Kazakhstan in the north and northwest, Kyrgyzstan and Tajikistan in the east and southeast, Turkmenistan in the southwest, and Afghanistan in the south. The republic also includes the Karakalpakstan Autonomous Republic, with its capital, Nukus (1992 est. pop., 182,000). The country is about one-tenth larger in area than the state of California.

The Uzbekistan land was once part of the ancient Persian Empire and was later conquered by Alexander the Great in the 4th century B.C. During the 8th century, the nomadic Turkic tribes living there were converted to Islam by invading Arab forces who dominated the area. The Mongols under Ghengis Khan took over the region from the Seljuk Turks in the 13th century, and it later became part of Tamerlane the Great’s empire and that of his successors until the 16th century. The Uzbeks invaded the territory in the early 16th century and merged with the other inhabitants in the area. Their empire broke up into separate Uzbek principalities, the khanates of Khiva, Bukhara, and Kokand. These city-states resisted Russian expansion into the area but were conquered by the Russian forces in the mid-19th century.
