The Charter of the United Nations is significant in global governance as it establishes the foundational principles guiding international relations and cooperation among member states. Ratified in 1945, the Charter promotes peace, security, human rights, and the principles of self-determination and equality among nations. It legitimizes interventions in cases of aggression and sets forth the framework for international institutions like the Security Council and the International Court of Justice. Ultimately, the Charter serves as a benchmark for assessing state behavior, aiming to prevent conflicts and foster a cooperative international community.
