At which conference were the terms of membership created for the United Nations

The terms of membership for the United Nations were created during the United Nations Conference on International Organization, commonly known as the San Francisco Conference. This conference took place from April 25 to June 26, 1945, and representatives of 50 countries gathered in San Francisco, United States, to draft and sign the United Nations Charter, the foundational treaty of the UN.

The criteria for membership were established in Chapter II of the United Nations Charter. Article 4 of the Charter sets forth the basic terms of membership: "Membership in the United Nations is open to all other peace-loving states which accept the obligations contained in the present Charter and, in the judgment of the Organization, are able and willing to carry out these obligations."

Extra: The United Nations was formed in the aftermath of World War II with the primary goal of preventing future conflicts and fostering international cooperation. The UN is an international organization that provides a forum for its member states to express their views, discuss issues, and work together on a wide range of matters, including peace and security, human rights, social and economic development, and international law.

The joining of new members after the UN's creation requires the recommendation of the Security Council and the approval of the General Assembly. Over time, the membership of the United Nations has expanded significantly to include nearly all recognized independent states.

It's important to note that the formation of the United Nations was a milestone in international relations, representing a collective global effort to promote peace and cooperation; it has since become a central fixture in diplomatic endeavors and global governance. The UN Charter established not only the terms for membership but also laid out the structure of the UN, including the General Assembly, Security Council, and other principal organs, and it set out the purposes and principles guiding the organization.
