The UN Charter, adopted in 1945, establishes the framework for the United Nations’ mission to maintain international peace and security, promote social progress, and ensure human rights. It defines the UN’s structure, including six main bodies like the Security Council, General Assembly, and International Court of Justice. The Charter emphasizes the peaceful settlement of disputes, discourages the use of force, and encourages cooperation between nations. It also upholds principles of sovereignty, equality of nations, and non-interference in internal affairs, aiming to prevent future conflicts and promote global cooperation.
