Final answer:
The UN established the International Court of Justice to promote the rule of law internationally. Located in The Hague, it serves as the principal judicial organ of the UN, addressing disputes between states and interpreting international law.
Step-by-step explanation:
The organization that the United Nations (UN) established to promote the rule of law internationally is the International Court of Justice (ICJ). The ICJ, also known as the World Court, is located in The Hague, Netherlands, and is the principal judicial organ of the UN. Its role is to settle legal disputes submitted to it by states and to give advisory opinions on legal questions referred to it by authorized international branches and agencies.
Founded in 1945 alongside the UN itself, the International Court of Justice is an essential component for upholding international law. It contributes to the UN's mission of maintaining international peace and security, protecting human rights, and promoting sustainable development by offering a judicial route for the resolution of international disputes.
