On 15 May 1999, Yeltsin survived another attempt of impeachment, this time by the democratic and communist opposition in the State Duma. He was charged with several unconstitutional activities, including the signing of the Belovezha Accords dissolving the Soviet Union in December 1991, the coup-d'état in October 1993, and initiating the war in Chechnya in 1994. None of these charges received the two-thirds majority of the Duma required to initiate the process of impeachment of the president.
