Boris Yeltsin
Boris Nikolayevich Yeltsin (1 February 1931 – 23 April 2007) was a Soviet politician who became the first president of Russia from 1991 to 1999.
Yeltsin abruptly transformed Russia's economy into a capitalist market economy by implementing an economic "shock therapy", nationwide privatization, and lifting of price controls. Economic collapse and inflation ensued. A small number of Russian oligarchs became very influential.
