Institute of National Remembrance

The Institute of National Remembrance – Commission for the Prosecution of Crimes against the Polish Nation is a Polish state research institute in charge of education and archives which also includes two public prosecution service components exercising investigative, prosecution and lustration powers. The IPN was established by the Polish parliament by the Act on the Institute of National Remembrance of 18 December 1998 through reforming and expanding the earlier Main Commission for the Investigation of Crimes against the Polish Nation of 1991, which itself had replaced a body on Nazi crimes established in 1945.In 2018, IPN's mission statement was amended by the controversial Amendment to the Act on the Institute of National Remembrance to include "protecting the reputation of the Republic of Poland and the Polish Nation".
