Social limitations
African discriminated for everything. They are not allowed to enter specific restaurants, they are forbidden to use public restroom, not allowed to enter theatre, etc
Political Limitations
Back then, their representative in the government is close to non existent
Economic limitations
Most companies only want to hire them for low-class hard labor with low pay. Not only that, it really hard for them to own a property during that period
hope this helps
Boats and ships are mainly over seas and on land is mainly carages
