Martial law in Poland (Stan wojenny w Polsce) existed between 13 December 1981 and . The government of the Polish People's Republic drastically restricted everyday life by introducing martial law and a military junta in an attempt to counter political opposition, in particular the Solidarity movement.
Since the late 1970s, communist Poland had been in a deep economic recession. Edward Gierek, First Secretary of the Polish United Workers' Party (PZPR), had obtained a series of large loans from foreign creditors to achieve better economic output, but they instead resulted in a domestic crisis. Essential goods were heavily rationed, which acted as a stimulus to establishing the first trade union in the Communist Bloc, known as Solidarity, in 1980. Gierek, who permitted the trade union to appear per the Gdańsk Agreement, was dismissed from his post less than a month later and confined to house arrest. Following countless strikes and demonstrations by employees of chief industrial regions, Poland was heading towards bankruptcy. The new First Secretary, General Wojciech Jaruzelski, was determined to put an end to the demonstrations by force if necessary.
On 13 December 1981, Jaruzelski announced the introduction of martial law in a televised speech, following the vote of the Council of State the previous day which formally authorised its introduction. An extraconstitutional military junta, the Military Council of National Salvation (WRON), was formed to rule Poland during the time. The Polish People's Army, Citizens' Militia (MO), ZOMO special paramilitary units, and tanks were deployed on the streets to demoralize demonstrators, begin regular patrols, control strategic enterprises, and maintain curfew. Intercity travelling without a permit was forbidden, food shortages intensified, and censorship was placed on all media and correspondence. The secret services (SB) wiretapped phones in public booths and state institutions. Thousands of opposition activists were imprisoned without trial, and although martial law was lifted in 1983, many political prisoners were not released until a general amnesty in 1986.
