Why are Asia and South American colored in a neutral color?

Well it all depends on what type of map your are referring to Asia and South America may or may not be colored in neutral. My map however shows them in full color. There are alot of maps created for different purposes so there is no way to know unless I know what map you are looking at. Usually, if they are grayed out, it means the creator of the map does not want you to focus on that area.

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)
