Amnesty of 1953

The Amnesty of 1953 was the largest amnesty in the history of the Soviet Union in terms of the number of the released persons. It was declared by the March 27, 1953 Decree of the Supreme Soviet of the Soviet Union on the Amnesty. Since it was signed by Kliment Voroshilov, it was initially known as the Voroshilov's amnesty. Later it has become known as Beria's amnesty, because it was initiated by March 26, 1953 Lavrenty Beria's draft. Between 1.2 million and 1.35 million persons were freed.
The amnesty was applied to:

all persons with imprisonment term up to 5 years
all persons convicted for malfeasance and economic crimes, as well as for some minor military crimes
all women with children of age up to 10 years, all pregnant women, all children of age up to 18 years
all men older than 55 and women older than 50
all persons with grave uncurable diseases

The amnesty was not applied to people with term over 5 years convicted for counter-revolutionary crimes, major theft of socialist property, banditism, and murder. Other acts of the amnesty included the reduction of imprisonment terms, dismissing unfinished criminal proceedings which fit the above criteria, etc.
The amnesty was followed with the considerable rise of criminal activities, therefore it was partially rolled back and many criminal amnestees were imprisoned again.
