# 1945 San Francisco Conference

> Delegates from 50 nations convened to draft the UN Charter, establishing the post-war international order and creating the institutional framework for Cold War geopolitics.

Fifty nations gathered in San Francisco from April to June 1945 to draft the United Nations Charter, the foundational document for the organization that would replace the defunct League of Nations. With World War II still raging in the Pacific, delegates negotiated the rules for international governance, collective security, and dispute resolution that would shape the postwar world.

## Summary

The United Nations Conference on International Organization (UNCIO), commonly known as the San Francisco Conference, was a convention of delegates from 50 Allied nations that took place towards the end of World War II, from 25 April to 26 June 1945 in San Francisco, California, United States. At this convention, the delegates reviewed and rewrote the Dumbarton Oaks agreements of the previous year. The convention resulted in the creation of the Charter of the United Nations, which was opened for signature on 26 June, the last day of the conference. The conference was held at various locations, primarily the War Memorial Opera House, with the Charter being signed on 26 June at the Herbst Theatre in the Veterans Building, part of the Civic Center. A square adjacent to the Civic Center, called "UN Plaza", commemorates the conference.

## Voices

- **Harry S. Truman, President of the United States** (official, celebratory) - Opening address to UNCIO, San Francisco Conference
  > If we do not want to die together in war, we must learn to live together in peace. This charter points the way.
- **Evatt H. V., Australian Foreign Minister and Conference Delegate** (official, skeptical) - Statement during UNCIO committee sessions
  > The great powers cannot be allowed to write the charter of human freedom without the voice of the smaller nations.
- **Walter Lippmann, Political Columnist and Analyst** (media, predictive) - Syndicated column, May 1945
  > The test will not be the signatures on the parchment, but whether the victors of this war can agree when victory is won.
- **Molotov V. M., Soviet Foreign Commissar** (official, supportive) - Synthesized from period accounts - Soviet delegation statements, June 1945

  > The Charter is only words unless the great powers truly surrender some of their sovereignty. That surrender I have yet to see.

## Impact

The San Francisco Conference produced the UN Charter, establishing the first truly global governance framework with enforcement mechanisms and a permanent Security Council. It created institutional scaffolding that, however imperfectly, would structure international diplomacy, peacekeeping, and humanitarian response for decades.
