On December 21, 2010, the UN General Assembly proclaimed March 24 as the International Day for the Right to the Truth Concerning Gross Human Rights Violations and for the Dignity of Victims. The date commemorates the assassination of Archbishop Óscar Romero of El Salvador on March 24, 1980, after he devoted his voice to defending victims of human rights violations in his country. The day rests on the principle that knowing the full truth about gross human rights violations — the circumstances, causes, and those responsible — is a fundamental right of victims, their families, and society as a whole, and that uncovering the truth helps combat impunity and strengthens the rule of law and reconciliation. The UN and human rights organizations worldwide mark the occasion with events honoring victims of violations, discussions on transitional justice mechanisms, and campaigns urging states to support truth commissions and independent investigations into serious abuses.
