Which instrument is the foundational treaty of the United Nations?

• A. Geneva Conventions
• B. UN Charter
• C. ICC
• D. Nuclear Non-Proliferation Treaty

Answer: (B)

The foundational instrument of the United Nations is the UN Charter. This document established the organization, defines its purposes (like maintaining international peace and security and promoting cooperation on economic, social, and humanitarian issues), and sets out how the UN operates, including its main organs and their powers. Because it creates the UN and provides the legal framework that all member states agree to, it stands as the binding source of the UN’s authority.

The other instruments mentioned play important roles but are not the founding basis. The Geneva Conventions regulate humanitarian law in armed conflict, but they predate the UN and exist independently as humanitarian treaties. The International Criminal Court is created by its own treaty, the Rome Statute, well after the UN’s founding. The Nuclear Non-Proliferation Treaty is a separate arms-control treaty. So the UN Charter is the foundational document because it is the treaty that establishes the UN and governs its mandate and structure.
