Twenty years ago this weekend, a group of Communist Party Politburo members and Soviet government officials attempted a coup d'état. They created an unconstitutional "committee on the state of emergency," isolated the Soviet president and removed him from power.

The events of that August were the result of fierce political struggle during the final stretch in our efforts to reform the Soviet Union.

During the years of perestroika, major changes transformed our country. The people supported glasnost; free, contested elections; and the beginning of the transition to market economics. But the bureaucracies of the Communist Party and the government eventually saw in those changes threats to their position.
