Throughout the rest of his time as President, Russia would be affected by many money problems, including inflation and corruption. Yeltsin decided to sell off many things the government had owned, such as oil and natural gas, and many government businesses, but these ended up falling into the hands of a small powerful group of billionaries, who became known as the oligarchs. In 1998, Russia suffered a large financial crisis. Yeltsin also started a war to stop the Chechnya part of Russia from breaking away.
