The period of political terrorism named the “Years of Lead” (Anni di Piombo) started in Italy at the end of the 1960s and lasted until the late 1980s. The social wounds of this bloody time are still not healed, and there is a social debate about the opportunity to concede forgiveness to those responsible for those crimes. Drawing from the intergroup forgiveness literature, we tested a model explaining under which conditions forgiveness towards terrorists could be supported by Italian citizens. The model was tested in two generations: 331 Italian citizens who were adolescents or adults during the terrorism period and 208 Italian young adults born after the end of the Years of Lead. Findings showed that restorative justice beliefs and sociocognitive variables, like outgroup empathy and trust, were uniquely linked to forgiveness towards the terrorists.
