50 nations sign the United Nations Charter in San Francisco
Two months after Roosevelt's death left the project without its chief architect, the conference he had set in motion came to its conclusion. On June 26, 1945 — nine weeks after delegates from 50 Allied nations gathered at San Francisco's War Memorial Opera House — representatives filed into the Herbst Theatre at the Veterans Building and signed the Charter of the United Nations. China signed first, as the first nation to have suffered Axis aggression. The Charter entered into force that October, and the organization Roosevelt had called the "Four Policemen" became the architecture of postwar international order.
Roosevelt conceived the UN's core structure — the "Four Policemen" framework that became the permanent Security Council — before he lived to see it ratified. Truman inherited both the conference and its closing speech, dedicating the moment to the dead of the war and warning that using the Charter for any single nation's advantage would betray them. The UN's founding in San Francisco embedded the United States at the center of the postwar international system it had designed.
QWhy did China get to sign the UN Charter before every other nation, including the United States?
The signing order was not alphabetical or diplomatic — it was symbolic. China signed first because it was recognized as the first nation to have fallen victim to an Axis power, with Japan's invasion of Manchuria dating to 1931 and the broader war beginning in 1937. The decision was a deliberate statement about who had suffered longest. The other delegations followed in English alphabetical order after China took its place at the table in the Herbst Theatre on June 26, 1945.
QHow did Stalin end up securing two extra UN votes without getting what he originally asked for?
Stalin's opening position at the Dumbarton Oaks negotiations was that all sixteen Soviet republics should receive individual UN membership — effectively giving the USSR sixteen votes in the General Assembly. The request was rejected, but at Yalta in February 1945, Roosevelt and Churchill agreed to a compromise: Belarus and Ukraine would be admitted as founding members alongside the Soviet Union itself. Both republics were still firmly under Moscow's control. The concession gave Stalin three seats in the General Assembly while the United States had one — a disparity that rankled American critics of the UN for decades.
QWhat happened to the one Allied nation that was conspicuously missing from the San Francisco Conference?
Poland had signed the original 1942 Declaration by United Nations — the document that gave the organization its name — but was barred from the San Francisco Conference because the Allied powers could not agree on which Polish government was legitimate. The Soviet-backed provisional government in Warsaw and the London-based government-in-exile each claimed authority. The standoff lasted through the entire conference. Poland finally signed the Charter on October 15, 1945, three weeks before it entered into force, and was retroactively counted as the 51st founding member of an organization whose founding conference it had not been permitted to attend.
