Who were the small group of rich people in Russia who owned everything?

The small group of rich people in Russia who owned a significant portion of the country's wealth and resources are often referred to as the "oligarchs." Emerging in the 1990s after the collapse of the Soviet Union, these individuals capitalized on the privatization of state assets, gaining control over key industries such as oil, gas, and metals. Their influence has been substantial in both the economy and politics of Russia, often leading to close ties with the government. This concentration of wealth and power has been a significant factor in shaping modern Russian society and its economic landscape.
