The political impacts that Europeans left for Africa were good and bad. The colonies made powers in a local government which was a more structured and organized government. Many countries have the same political system they were given back when the Europeans introduced it. The Europeans also introduced constitutions and democracies. Unlike government they brought nationalism. Nationalism caused many wars and revolutions. The nationalism would be bad for the Europeans later.
Europeans brought the new technologies they made with them. they made industries to get supplies that were necessary for the modern technologies. This made railroads and roads so they could transport the goods. Many African countries needed the markets to be what they are now. And that is a good thing now, but the Europeans didnt pay the natives very much or at all for their work.
The first cultural changes were religions, they were mostly changed to christians. The missionaries started making hospitals, dispensaries, schools, and colleges. This started teaching africans about History, Math, Science, and Language. All of the effects were important in shaping african culture.
