Answer:
Once the race is understood as a social construct, several policies and social issues will be created to regulate the members of that race, and traditionally these policies create segregation and prejudice.
Explanation:
I think that two good examples to illustrate this point is the Jim Crow system in the Southern of the USA, and the eugenics policies executed by the Nazis. Both were influenced by the racial racism that emerged in the late 18th century but became strong in the 19th century. When we analyze their practices, it's clear the idea of segregation, to create a strong race, to avoid the racial mixture, but above all else, to control races considered degenerated or dangerous, avoiding their spread. This happened with black people on the US (Jim Crow system), and with the Jews and several other social/racial minorities in Europe under the shadow of the Nazis.
Colonists had many reasons for leaving Europe and coming to the New World. Some only had a small area of farming land in Europe and expected to get bigger farms in America. Others were fed up with wars and rebellions that went on in Europe and made it unstable. They wanted peace and a quiet life. Another group thought it was easy to make money and get rich quickly in America. Farmers in the south saw a chance to earn a lot by growing and selling tobacco.
But most people came for religious reasons. Many European kings and queens forced their people to have the same religion that they had. Most settlers came to America because they wanted religious freedom.
