How did the Monroe Doctrine influence America's involvement in future conflicts?

In a speech to Congress in 1823, President James Monroe warned European powers not to attempt further colonization or otherwise interfere in the Western Hemisphere, stating that the United States would view any such interference as a potentially hostile act. Later known as the Monroe Doctrine, this policy principle would become a cornerstone of U.S. diplomacy for generations.

U.S. Motivations Behind the Monroe Doctrine

By the early 1820s, many Latin American countries had won their independence from Spain or Portugal, with the U.S. government recognizing the new republics of Argentina, Chile, Peru, Colombia and Mexico in 1822. Yet both Britain and the United States worried that the powers of continental Europe would make future attempts to restore colonial regimes in the region. Russia had also inspired concerns of imperialism, with Czar Alexander I claiming sovereignty over territory in the Pacific Northwest and banning foreign ships from approaching that coast in 1821.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
