How did centers of the world power shift feom the period before world war 1 to the peroid after world war 2

The Center of powers shifted from Western Europe to  the USA and the USSR

Explanation:

the three-fifths compromise was proposed by james wilson and roger sherman, who were both delegates for the constitutional convention of 1787. however, the three-fifth compromise has its roots further back in history, dating back to the continental congress in 1783. the compromise was a result of the apportionment of taxes being related to land values.

hope this : )

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)
