How did John Quincy Adams help resolve the claim?

John Quincy Adams played a pivotal role in resolving the claim related to the Adams-Onís Treaty of 1819, which settled territorial disputes between the United States and Spain. As Secretary of State, he negotiated the treaty, which not only ceded Florida to the U.S. but also defined the boundaries of the Louisiana Purchase. Adams's diplomatic efforts helped to strengthen U.S. territorial integrity and reduce tensions with Spain. His work laid the foundation for future U.S. expansion and solidified his reputation as a skilled diplomat.
