The United Nations General Assembly designated January 27—the anniversary of the liberation of Auschwitz-Birkenau-as International Holocaust Remembrance Day. The Holocaust profoundly affected countries in which Nazi crimes were perpetrated, but also had universal implications and consequences in many other parts of the world. Member States share a collective responsibility for addressing the residual trauma, maintaining effective remembrance policies, caring for historic sites, and promoting education, documentation and research, seven decades after the genocide. This responsibility entails educating about the causes, consequences and dynamics of such crimes so as to strengthen the resilience of young people against ideologies of hatred.
