The Europeans thought that they deserved to colonized the people who were native to Africa. They didn't pay any attention to the Africans boarder or tribes and just overruled them with there own political borders. Then there is obviously, the slave trading business. 

The Europeans must have thought that were better because you wouldn't treat someone who you view as your equal that way.
