Nazi Germany and its collaborators murdered an estimated 200,000 to 500,000 Romani people. Methods included mass shootings, gassing, and forced labor. The genocide was parallel to, and in some places simultaneous with, the Holocaust.
Romani victims were not a central focus of the Nuremberg trials. Recognition has grown slowly; Germany formally recognized the genocide in the 1980s and later established memorials. Many countries still under-acknowledge the Porajmos relative to the Holocaust.
