Why did Africans Americans who moved to northern cities still face limitations because of their race?

I believe the answer is segregation

African Americans who moved to northern cities still faced limitations because they were considered inferior (Racism).

Explanation:

African Americans and people of color in general were always viewed as inferior individuals than 'white people'. This is the reason why they were taken from their homelands and treated as slaves for labor. The ones who moved to the industrialized cities of the north still faced many challenges because they could not vote, be part of the government or own land. Most of them had to work as servants for the rich householders. This situation changed over time and they could enjoy the same rights as anyone else. However, many people still feel they are inferior and discriminate against them.
