What did spain do after the american revolution to discourage america settlements west of the appalachian mountain

One of the things that Spain did after the American Revolution to discourage American settlements west of the Appalachian Mountains was to fortify many of their pre-existing forts in the area to make them seem more intimidating. 

Explanation:

This is because they closed the ports to New Orleans which made American trade more difficult and enraged the society.

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)
