Boris Yeltsin
In 1985, Mikhail Gorbachev made Yeltsin the leader of the city of Moscow. Yeltsin became one of the more liberal members of Gorbachev's government, and he often complained that Gorbachev's reforms were not doing enough. Eventually, in 1987, he had an argument with Gorbachev and ended up being kicked out. Yeltsin then became determined to get revenge. After Russia's elections in 1989, Yeltsin became leader of the Russian Parliament. It was his idea to create the office of President of Russia in the first place.
