The
constitutional crisis of 1993 was a political stand-off between the
Russian president Boris Yeltsin and the
Russian parliament that was resolved by using military force. The relations between the president and the parliament had been deteriorating for some time. The
constitutional crisis reached a tipping point on September 21, 1993, when President Yeltsin aimed to dissolve the country's legislature (the
Congress of People's Deputies and its
Supreme Soviet), although the president did not have the power to dissolve the parliament according to the constitution. Yeltsin used the results of the
referendum of April 1993 to justify his actions. In response, the parliament declared that the president's decision was null and void, impeached Yeltsin and proclaimed vice president
Aleksandr Rutskoy to be acting president.
