Mass human rights violations, such as those which occurred during the Albanian Dictatorship (1945–1991), can impact citizens across generations. Decades later, the lives of families and community members are often defined by efforts to achieve justice and prevent similar future experiences. Existing research shows that social identities predict how survivors experience, understand, and cope with these violations. On the other hand, social identities can also inform societal-level strategies of peace and reconciliation in the aftermath. However, it is not known how ingroup norms (e.g., familial, civic) impact intergenerational understandings of and responses toward transitional justice. To explore this, we analyze the accounts of first-generation survivors of human rights violations during the Albanian Dictatorship and their descendants (n = 52). The data were analyzed through reflexive thematic analysis informed theoretically by the Social Identity Approach and conceptually by transitional justice frameworks. The findings indicate that families take a central role in determining how past harms are understood and responded to, and that associated identity-based norms (e.g., family norms) inform transmission of knowledge about past harms and appropriate forms of justice. Identity-based norms can also determine which justice processes are deemed acceptable for the next generation/s to engage in (e.g., peaceful responses, documentation of past harm, education of new generations, and fights for democracy). Implications for social identity and justice theories, as well as for practice, are discussed. Public Significance Statement: The present study suggests that family and civic social norms can guide intergenerational understanding and coping with mass human rights violations as well as responses to transitional justice processes (e.g., nonvengeance, documenting violations, democracy building) in the aftermath. As such, social norms should be integrated in the efforts for peace and reconciliation building. The findings also highlight the different benefits and harms of transmitting knowledge of the violations across generations. [ABSTRACT FROM AUTHOR]
