Which 1945 conference's agreements laid groundwork for the UN and postwar order?

• A. Potsdam Conference
• B. Yalta Conference
• C. San Francisco Conference
• D. Tehran Conference

Answer: (C)

The main idea here is how a formal international framework for peace was created. In 1945, delegates gathered at the San Francisco Conference to draft and adopt the charter that would establish the United Nations. This charter laid out the organization’s purposes, like preserving peace and security, promoting human rights, and fostering cooperation among nations, and it set up the key institutions—the General Assembly and the Security Council with permanent members and a veto—that would govern international relations after the war. That decision to create a standing international body with a defined structure gave the postwar order its legal and organizational backbone.

Tehran had focused on wartime strategy and alliance coordination, not on building the UN. Yalta discussed postwar goals and some principles for international cooperation, but it did not create the UN charter. Potsdam dealt with postwar administration and concrete talks about implementing decisions, especially regarding Germany, rather than establishing the global framework itself. So the San Francisco Conference is the one whose agreements forged the United Nations and the framework for the postwar order.
