Of course, the Scramble for Africa was of great importance to Africans of the time. It led to them being colonized by European countries. This also affected their descendants. This is because the fact that they were colonies ended up making it harder for their countries to develop politically and economically once they became independent.
For the world as a whole, a major consequence of the Scramble for Africa was the sort of imperial rivalries that helped to cause WWI. The competition for Africa helped to cause tensions, particularly between Germany one the one side and England and France on the other.
