Kumertau is a city in the Republic of Bashkortostan, Russia. It is located on the Belaya River, approximately 120 kilometers south of Ufa, the capital of Bashkortostan. Kumertau was founded in 1947 as a closed city to support the construction of a secret military plant. The city grew rapidly during the Soviet era, and by the 1980s, it had a population of over 60,000 people. After the collapse of the Soviet Union, Kumertau's economy suffered, and the city's population declined. However, in recent years, Kumertau has seen a revival, thanks to the development of new industries and the influx of new residents. Today, Kumertau is a thriving city with a population of over 65,000 people. It is home to a number of cultural and educational institutions, including the Kumertau State Institute of Technology and the Kumertau Museum of Local History.
