Jerzy Popiełuszko was a Roman Catholic priest from Poland, associated with the Solidarity union. He was murdered by three agents of the Polish communist internal intelligence agency, the Służba Bezpieczeństwa, (English: Security Service of the Ministry of Internal Affairs) who were shortly thereafter tried and convicted of the murder. He has been recognized as a martyr by the Catholic Church, and was beatified on June 6, 2010.
