On 13 Dec 81, Prime Minister General Wojciech Jaruzelski declared Martial Law in Poland, closing the borders, instituting military patrols, imposing a strict curfew, and censoring all media. Food and other necessities were scarce and rationed, and any travel without a permit was prohibited.
These photographs of Gdańsk are by Bogusław Nieznalski, from the exhibit Stan Wojenny [or Martial Law; literally “state of war”]. You can read some eyewitness accounts of that December here, as well as a brief summary of the events of the time. More photos here.
