Which was the first nation to ratify the United Nations Charter in 1945?

A quick skim around the web suggests that it was the United States, on August 8, 1945.

Actually, it was Nicaragua. The USA was among the 50 to sign the document on June 26, 1945. The USA then ratified the charter on July 28. Nicaragua, however, ratified the charter on July 6.

The date of August 8 is the USA's date of deposit of ratification. In that case, the USA did beat Nicaragua by several weeks (September 6).

(The U.S. ratification followed that of Nicaragua and El Salvador.) The United Nations officially came into existence on October 24, 1945, after the United States, the Soviet Union, the United Kingdom, China, and France, as well as a majority of the other signatories, had ratified the United Nations Charter.
