Bilateral diplomatic relations between the United States and Portugal date from the earliest years of the United States. Following the Revolutionary War, Portugal was the first neutral country to recognize the United States. On February 21, 1791, President George Washington opened formal diplomatic relations, naming Col. David Humphreys as U.S. Minister Resident. Subsequent envoys were given the title Minister Plenipotentiary.
