Polish Solidarity movement and martial law

Pope John Paul II provided a moral focus for anti-communism; a visit to his native Poland in 1979 stimulated a religious and nationalist resurgence centered on the Solidarity movement trade union that galvanized opposition and may have led to his attempted assassination two years later. In December 1981, Poland's Wojciech Jaruzelski reacted to the crisis by imposing a period of martial law. Reagan imposed economic sanctions on Poland in response. Mikhail Suslov, the Kremlin's top ideologist, advised Soviet leaders not to intervene if Poland fell under the control of Solidarity, for fear it might lead to heavy economic sanctions, resulting in a catastrophe for the Soviet economy.
