What is the only day that congress has to meet(at a minimum) annually?

The First Monday in December.

“The Congress shall assemble at least once in every Year, and such Meeting shall be on the first Monday in December, unless they shall by law appoint a different day”

the correct answer is the supreme court.this is because when a person was accused of a crime during rome they brought him to a place to decide his fate also known as a jury

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)
