On the Sept. 21, 1993 Yeltsin would dissolve the Supreme Soviet and the Congress of People's Deputies. Two days later, the constitutional court (think Supreme Court) ruled that Yeltsin violated the constitution, and could be impeached - and with a quorum congress voted to impeach Yeltsin. Additionally, congress voted to have simultaneous parliamentary and presidential elections, which Yeltsin responded to by cutting off electricity, phone service, and hot water to the parliamentary (nicknamed the white house) building.

This culminated with tanks shelling the parliamentary building. Yeltsin would say this:

Those, who went against the peaceful city and unleashed bloody slaughter, are criminals. But this is not only a crime of individual bandits and pogrommakers. Everything that took place and is still taking place in Moscow is a pre-planned armed rebellion. It has been organized by Communist revanchists, Fascist leaders, a part of former deputies, the representatives of the Soviets. Under the cover of negotiations they gathered forces, recruited bandit troops of mercenaries, who were accustomed to murders and violence. A petty gang of politicians attempted by armed force to impose their will on the entire country. The means by which they wanted to govern Russia have been shown to the entire world. These are the cynical lie, bribery. These are cobblestones, sharpened iron rods, automatic weapons and machine guns. Those, who are waving red flags, again stained Russia with blood. They hoped for the unexpectedness, for the fact that their impudence and unprecedented cruelty will sow fear and confusion.

The parliament had many allies in the military, but did not pursue the allegiance of the NCOs, which was likely a major factor in the eventual victory of Yeltsin.

the kicker: Yeltsin was elected to the Supreme Soviet with 89% of the vote in 1989.

147 people would die.
