Martial law in Poland (Polish: Stan wojenny w Polsce) refers to the period of time from December 13, 1981 to July 22, 1983, when the authoritarian government of the People's Republic of Poland drastically restricted normal life by introducing martial law in an attempt to crush political opposition. Thousands of opposition activists were interned without charge and as many as 100 people were killed. Although martial law was lifted in 1983, many of the political prisoners were not released until the general amnesty in 1986.
Led by General of the Army Wojciech Jaruzelski and the Military Council of National Salvation (Wojskowa Rada Ocalenia Narodowego, WRON) usurped for itself powers reserved for wartime, hence the name. The plan was presented to the government of the Soviet Union before the declaration in March 1981.
