Bishkek, formerly Pishpek and Frunze, is the capital and the largest city of Kyrgyz Republic or Kyrgyzstan.Bishkek is also the administrative centre of Chuy Province which surrounds the city, even though the city itself is not part of the province but rather a province-level unit of Kyrgyzstan.According to the post-Soviet ideology, the name is thought to derive from a Kyrgyz word for a churn used to make fermented mare's milk, the Kyrgyz national drink, which is rather debatable.Founded in 1825 as a Khokand fortress of "Pishpek" to control local caravan routes and to get tribute from Kyrgyz tribes, on 4 September 1860 the fortress was destroyed by Russian forces led by colonel Zimmermann, with approval of the Kyrgyz. In 1868 a Russian settlement was founded on the fortress's spot, adopting its original name - Pishpek, within the General Governorship of Russian Turkestan and its Semirechye Oblast. In 1925 the Kara-Kirghiz Autonomous Oblast was created in Russian Turkestan, promoting Pishpek as its capital. In 1926 the city was given name Frunze, after the Bolshevik military leader Mikhail Frunze, which was born here. In 1936 the city of Frunze became the capital of the Kirghiz Soviet Socialist Republic during the final stages of the national delimitation in the Soviet Union.In 1991, the Kyrgyz parliament changed the capital's name to Bishkek.Bishkek is situated at about 800 metres altitude just off the northern fringe of the Kyrgyz Ala-Too range, an extension of the Tian Shan mountain range, which rises up to 4,855 metres and provides a spectacular backdrop to the city. North of the city, a fertile and gently undulating steppe extends far north into neighbouring Kazakhstan. The Chui River drains most of the area. Bishkek is connected to the Turkestan-Siberia Railway by a spur line.Bishkek is a city of wide boulevards and marble-faced public buildings combined with numerous Soviet-style apartment blocks surrounding interior courtyards and, especially outside the city centre, thousands of smaller privately built houses. It is laid out on a grid pattern, with most streets flanked on both sides by narrow irrigation channels that water the innumerable trees which provide shade in the hot summers.
