[1] The convention resulted in the creation of the United Nations Charter, 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.

[5] The conference directly invited four additional countries: Denmark (newly liberated from Nazi occupation), Argentina and the Soviet republics of Belarus and Ukraine.

[1] The participation of Belarus and Ukraine at the conference came as a result of Roosevelt and Churchill's concession to Joseph Stalin, the Soviet leader who had originally requested all republics of the Soviet Union to have membership in the United Nations, but the US government launched a counterproposal in which all US states would obtain membership in the United Nations.

The counterproposal encouraged Stalin to attend the Yalta Conference by accepting only Ukraine and Belarus's admission to the United Nations.

[1] That was intended to ensure a balance of power within the United Nations, which, in the opinion of the Soviets, was unbalanced towards the Western countries.

For that purpose, modifications were made to the constitutions of the two republics in question so that Belarus and Ukraine's international legal subjects were limited while they were still part of the Soviet Union.

[citation needed] Poland, despite having signed the Declaration by United Nations, did not attend the conference because there was no consensus on the formation of the postwar Polish government.

This conference is proof in itself of the new conception of neighborliness and unity which must be recognized in world affairs.Due to the fact that President Roosevelt, who was supposed to host the conference, died on 12 April 1945, the delegates held a commemorative ceremony in Muir Woods National Monument Cathedral Grove to place a comparative plaque for him.

The leadership of the commissions and technical committees consisted of a chairman and a rapporteur; these positions were divided among all of the national delegations.

It prepared agenda and working papers for discussion, compiled minutes and records of meetings, and provided the array of standard services required by any international conference.

[1] The issue of the veto power of the permanent members of the Security Council proved to be an obstacle on the quest to reach agreement on the United Nations Charter.

However, the great powers insisted that the provision was vital and stressed the fact that the United Nations was for the greater responsibility in maintaining world peace.

As he submitted the final text of the Charter to the assembly, he said: "The question we are about to solve with our vote is the most important thing that can happen in our lives."

[5] US President Harry S. Truman's closing speech said: The Charter of the United Nations which you have just signed is a solid structure upon which we can build a better world.

[5] In 2019, the General Assembly, recognizing of the seventy-fifth anniversary of the conference, proclaimed April 25 as International Delegate's Day.
