 Constitutionally the Congress was required to meet every year, but actually due to the turbulent events during these years it met from two to three times a year.The Congress gathered in the Grand Kremlin Palace (except the Xth congress that gathered in the White House) and held a total of ten sessions.Its last session was held after the presidential dissolution decree, and was interrupted by armed attack on the White House by forces loyal to the president of Russia, Boris Yeltsin.
