Kyrgyzstan, officially the Kyrgyz Republic, also known as Kirghizia, is a landlocked country in Central Asia. Kyrgyzstan is bordered by Kazakhstan to the north, Uzbekistan to the west, Tajikistan to the south, and China to the east. Its capital and largest city is Bishkek. Ethnic Kyrgyz make up the majority of the country's six million people, followed by significant minorities of Uzbeks and Russians. The Kyrgyz language is closely related to other Turkic languages, although Russian remains spoken and is an official language, a legacy of a century of Russification. Ninety percent of Kyrgyzstan's population are Muslim, with the majority of its population following Sunni Islam. In addition to its Turkic origins, Kyrgyz culture bears elements of Iranic, Mongolian and Russian influence.
