What events or circumstances may have led president Monroe or his secretary of state John Quincy Adams to want to protect the newly independent Latin American states?

President Monroe and Secretary of State John Quincy Adams were motivated to protect the newly independent Latin American states due to a combination of geopolitical concerns and a desire to promote democracy. The success of these revolutions against colonial powers, particularly Spain, inspired American ideals of self-determination and liberty. Additionally, they feared that European powers might attempt to reassert control over Latin America, which could threaten U.S. interests and influence in the region. Thus, the Monroe Doctrine was established to assert that any European intervention in the Americas would be viewed as a hostile act against the United States.
