In history, some European countries sold black slaves, but now many European countries have black people. How do they get equal rights with local whites?

The main purpose of black trafficking in European history is to provide labor. At that time, the land on the European continent had been developed almost, so Europeans opened up new land in America and Asia. However, the United States has a fertile and vast land and a sparse population, so European colonists sold blacks to the United States as labor, while there were few in Europe, so the problem of blacks in Europe was basically ignored.

When contemporary European democracy and civilization were relatively developed, African blacks began to immigrate to Europe in large numbers, especially France and Italy. Of course, although these blacks enjoy certain rights in the local area, they are still very suppressed, but they have not yet attracted attention.
