The significance of the Rwandan Genocide in world history lies in its sheer brutality and the international community's failure to intervene. Occurring in 1994, this horrific event resulted in the massacre of approximately 800,000 Tutsi and moderate Hutu individuals in just 100 days. The genocide highlighted issues of ethnic conflict, colonial legacy, and the consequences of international inaction. It prompted global discussions on humanitarian intervention and genocide prevention, leading to reforms in international law regarding crimes against humanity. The legacy of the genocide also spurred efforts to promote reconciliation and justice in Rwanda and beyond.
