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).[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]
