Ridder (Kazakh: Риддер, romanized: Ridder; formerly known as Leninogorsk; Russian: Лениногорск) is a city in the East Kazakhstan Region in northeastern Kazakhstan. Its population is approximately 50,500 (2009 census results).[3] The city is in the south-western Altai Mountains and northeast of the region's capital, Oskemen, along the Ulba River, at an elevation higher than 700 metres.[4] Ridder is the source of the E40 motorway.
History
[edit]The fact that Altai Krai is rich in natural deposits was discovered during Empress Catherine the Great's reign. Ridder was founded in 1786 when 9 troops of men were sent to the Altai region to search for natural resource deposits. On May 31, 1786 an officer, Philip Ridder, found a rich deposit containing gold, silver and other metals.[5]
During the early 20th century Ridder experienced a number of foreign concessions, revolution and Civil war. On February 10, 1934, Ridder was designated a town.[6] In 1941 Ridder was renamed to Leninogorsk (for Lenin).[citation needed]
During World War II Leninogorsk produced about 50% of the high-quality lead in the whole Soviet Union. In 2002 the city returned to its original name, Ridder.[7]
Climate
[edit]Ridder has a warm-summer humid continental climate (Köppen climate classification Dfb) with mild summers and very cold winters.
