In which year did the Warsaw Pact officially dissolve?

The Warsaw Pact was officially dissolved in the year 1991. The Warsaw Pact had been formed in 1955 in response to the decision made by the United States and its western European allies to add West Germany in the North Atlantic Treaty Organization. The Warsaw Pact was a political and military alliance between the Soviet Union and several Eastern European countries (Albania, Poland, Romania, Hungary, East Germany, Bulgaria, and Czechoslovakia).

When Eastern European members broke away from the Soviet Union, they became self governing and had sovereignty over their own territories and residents. As the Pact was disabling itself, Eastern European members cut themselves loose from Moscow one by one. By 1991 the Soviet Union had lost its “friends” and had entered into a time of turmoil. The Warsaw Pact had absolutely no authority when it was finally dissolved.

Some Soviet politicians publicly stated that the social, economic, and political interests of the Soviet Union were better served when the Warsaw Pact totally fell apart. It caused the country's government to focus on the critical needs of all the people. The country spent more money on social changes, infrastructure, and the environment. The military got less. When the Warsaw Pact came to an end, this was another sign that the Soviet Union had lost control over its former allies and that the Cold War between powers in the Eastern Bloc and powers in the Western Bloc was coming to an end.
