UNESCO member states proclaimed this day in 1995 — the year the UN designated as the International Year for Tolerance and UNESCO marked its 50th anniversary — following the adoption of the Declaration of Principles on Tolerance, signed on November 16 that same year. The declaration defines tolerance as respect, acceptance, and appreciation of the rich diversity of the world's cultures, forms of expression, and human qualities. It is not a concession or indulgence but an active attitude grounded in recognizing universal human rights and the fundamental freedoms of others. The day confronts intolerance, discrimination, and hatred in all forms — religious, ethnic, or cultural. UNESCO marks the occasion by awarding the Madanjeet Singh Prize, honoring individuals and institutions that have advanced tolerance and non-violence, alongside conferences and educational and cultural events worldwide reinforcing coexistence among diverse cultures.
