Lasting a little more than 100 years (1880-1990), whst were the
effects of colonialism in Africa? Can colonialism be seen as positive?

Hope this helps.

Colonialism is generally a good thing and this is for many different
reasons, i will list those here:
.-When a country is taken over it is typically done by larger countrys
which have strong trade policies already in place.
.-When a country is taken over there is usually a reason for it, most
of the time it is for the gain of certain companies, or person.
.- These companys or person bring their services / money to the
region. They give jobs.
I know theres more i was just sugesting that we think of the overall
thoughts of colonialism, not just the effects in certain countrys.
However there are some downsides, for instance lets look at Cuba!
