The region within modern day Uzbekistan has a long history of important civilization, and served as an important link in cultural and economic exchange between Persia in the West and Inner and East Asia for over two thousand years. Historically, the region of modern day Uzbekistan was inhabited by Persian speakers, or Tajiks, and Turkic speakers living alongside one another. Many of Central Asia's historically important cultural and economic centers are found in today's Uzbekistan, including Samarkand, Tashkent and Bukhara. This region was the center of a great deal initial resistance to the Mongol invasion in the early 13th century. After the Mongol Empire began to weaken and fragment an ethnic Turk, Timur i-Lenk, aka Tamerlane, or Timur the Lame, established an dynasty in this region.
Russia conquered the territory of present-day Uzbekistan in the late 19th century. Stiff resistance to the Red Army after the Bolshevik Revolution was eventually suppressed and a Soviet socialist republic established in 1924. During the Soviet era, intensive production of cotton, as well as grain, led to overuse of agrochemicals and the depletion of water supplies, which have left the land poisoned and the Aral Sea and certain rivers dry. Independent since 1991, the country seeks to gradually lessen its dependence on agriculture while developing its mineral and petroleum reserves. Current concerns include terrorism, economic stagnation, and the weakening of human rights and democratization.
