What did President James Monroe do to promote nationalism when he took office in 18177 A. He embarked on a goodwill tour of the country. B. He negotiated a deal with Spain to cede Florida to the United States. C. He chartered the First National Bank of the United States D. He authorized war with Great Britain​

The correct option is B

Explanation:

The Monroe Doctrine, synthesized in the phrase "America for the Americans," was elaborated by John Quincy Adams and was attributed to Monroe. James Monroe proposed the "doctrine" in which he addressed the Europeans with the intention that none of the countries of that continent would interfere in America. "America for the Americans", meant that Europe could not invade or have colonies on the continent. As the process of Imperialism was taking place after the defeat of Napoleon in Waterloo, the doctrine deduced that the European powers took care of Asia and Africa but that America belonged to the Americans.

Between 1817 and 1818 Andrew Jackson, pretending the occupation of the island of Amelia by pirates and the attacks of the Seminoles against Georgia invaded Florida; Spain, involved in the process of American emancipation, was unable to defend its possession and in 1819 preferred to cede this territory in exchange for canceling the debts that Spanish citizens had with US merchants worth five million dollars. The acquisition of Florida finished closing the Atlantic facade of the Union.
