Boris Nikolayevich Yeltsin (1 February 1931 – 23 April 2007) was a Russian politician and statesman who served as President of Russia from 1991 to 1999. He was a member of the Communist Party of the Soviet Union (CPSU) from 1961 to 1990. He later stood as a political independent, during which time he was viewed as being ideologically aligned with liberalism.
Yeltsin was born in Butka, Ural Oblast. Growing up in Kazan and Berezniki, he worked in construction after studying at the Ural State Technical University. After joining the Communist Party, he rose through its ranks, and in 1976, he became First Secretary of the party's Sverdlovsk Oblast committee. Yeltsin was initially a supporter of the perestroika reforms of Soviet leader Mikhail Gorbachev. He later criticized the reforms as being too moderate and called for a transition to a multi-party representative democracy. In 1987, he was the first person to resign from the Politburo of the Communist Party of the Soviet Union, which established his popularity as an anti-establishment figure and after which he earned the reputation of the leader of the anti-communist movement. In 1990, he was elected chair of the Russian Supreme Soviet and in 1991 was elected president of the Russian Soviet Federative Socialist Republic (RSFSR), becoming the first popularly-elected head of state in Russian history. Yeltsin allied with various non-Russian nationalist leaders and was instrumental in the formal dissolution of the Soviet Union in December of that year. With the dissolution of the Soviet Union, the RSFSR became the Russian Federation, an independent state. Through that transition, Yeltsin remained in office as president. He was later re-elected in the 1996 Russian presidential election, which critics assert was rigged.
