Hello!

The continent which benefitted most during the first 100 years of the Columbian Exchange was Europe

Hope this helps!!

they were treated very badly. they were targeted by white supremacists and other groups, like the klu klux klan, even after coming back to the country as veterans. they were seen as inferior and gave the african americans new found motivation to fight against this racial injustice. 

it was seen as enticement to accept british domination.
