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
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).
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
Ridder has a warm-summer humid continental climate (Köppen climate classification Dfb) with mild summers and very cold winters.
