out in June 1976, and although they were forcibly suppressed, the planned price increases were suspended. High foreign debts, food shortages, and an outmoded industrial base compelled a new round of economic reforms in 1980. Once again, price increases set off protests across the country, especially in the Gdańsk and Szczecin shipyards. Gierek was forced to grant legal status to Solidarity and to concede the right to strike. (Gdańsk Agreement). Shortly thereafter, in early September 1980, Gierek was replaced by Stanisław Kania as General Secretary of the party by the Central Committee, amidst much social and economic unrest. Kania admitted that the party had made many economic mistakes, and advocated working with Catholic and trade unionist opposition groups. He met with Solidarity leader Lech Wałęsa, and other critics of the party. Though Kania agreed with his predecessors that the Communist Party must maintain control of Poland, he never assured the Soviets that Poland would not pursue actions independent of the Soviet Union.

In 1982, Jaruzelski revitalized the Front of National Unity, the organization the Communists used to manage their satellite parties, as the Patriotic Movement for National Rebirth. In 1985, Jaruzelski resigned as prime minister and defence minister and became chairman of the Polish Council of State, a post equivalent to that of president or a dictator, with his power centered on and firmly entrenched in his coterie of "LWP" generals and lower ranks officers of the Polish People's Army. Breakdown of autocracy The attempt to impose a naked military dictatorship, notwithstanding, the policies of Mikhail Gorbachev stimulated political reform in Poland. By the close of the tenth plenary session in December 1988, the Polish United Workers Party was forced, after strikes, to approach leaders of Solidarity for talks. From 6 February to 15 April 1989, negotiations were held between 13 working groups during 94 sessions of the roundtable talks. These negotiations resulted in an agreement that stated
