Kyrgyzstan is a small country located to the west of China and to the south of Kazakhstan. It was a republic of the Soviet Union until becoming independent in 1991. Most of Kyrgyzstan is mountainous, with many peaks exceeding 4,000 meters (13,123 feet), and a few taller than 7,000 meters (22,965 feet). The capital and largest city is Bishkek. The largest ethnic group is the Kyrgyzs; other groups include the Uzbeks, Russians, and many smaller ethnic groups. Kyrgyz and Russian are the official languages, with Uzbek being a major language in the areas of western Kyrgyzstan with large Uzbek populations. Kyrgyzstan’s economy is largely based on agriculture and resource extraction. The Kyrgyz people were historically nomads who roamed the mountains with their herds, and the country still produces wool, meat, and cotton. Kyrgyzstan also has deposits of gold, uranium, and mercury, among other metals.
