Final answer:
John Quincy Adams made significant contributions to U.S. foreign policy, negotiating the Adams-Onis Treaty and establishing diplomatic relations with European countries. While he didn't draft the Monroe Doctrine, he strongly supported it.
Step-by-step explanation:
John Quincy Adams, the sixth president of the United States, made significant contributions to U.S. foreign policy. One of his major accomplishments was negotiating the Adams-Onis Treaty in 1819. This treaty secured the United States' acquisition of Florida from Spain, expanding the nation's territory.
Adams also played a crucial role in establishing diplomatic relations with European countries during his tenure as U.S. ambassador to several nations. His diplomatic efforts helped strengthen the United States' presence and reputation on the international stage.
While Adams did not draft the Monroe Doctrine, as commonly believed, he strongly supported it during his presidency. The doctrine, issued by President James Monroe in 1823, warned European powers against colonizing or interfering in the affairs of the newly independent countries in the Americas.
