During the morning closed session of the last day of the Congress, Khrushchev, the Communist Party Secretary, took the opportunity to give a stinging rebuke of the policies of Stalin, his late predecessor. Khrushchev denounced Stalin's cult of personality, and Stalin's apparent support of the concept of individuality. He went on to denounce a list of crimes committed by Stalin's supporters, many of which had previously been denied by the Soviet Union.
The speech shocked delegates to the congress, as it flew in the face of years of Soviet propaganda, which had claimed that Stalin was a wise, peaceful, and fair leader. After long deliberations, in a month the speech was reported to general public, but the full text was published only in 1989.
One of its most notable fallouts was the collapse of the United States Communist Party which had previously been composed of many die-hard Stalinists. Stalin's fall from grace left the party badly fractioned, and it never regained its former influence.
In the 1930s the party, in alliance with the Communist Party of China, conducted guerilla operations in the mountains of northern Korea against the Japanese and Kim became one of the party's guerilla leaders.
The TwentiethPartyCongress of the Soviet Communist Party was a bombshell with Nikita Khrushchev'sSecret Speech denouncing Stalin and the inauguration of destalinisation.
The partycongress approves reports of the party organs, adopts basic party policies and tactics, and elects members to the WPK Central Committee and the Central Auditing Committee.
The Congress of the CPSU was the gathering of the delegates of the Communist Party of the Soviet Union and its predecessors.
The frequency of partycongresses also varied with the meetings being annual events in the 1920s while no Congress was held at all between 1939 to 1952.
Between the congresses the party was ruled by the Central Committee, abbreviated as ЦК, "Tseka".
