Why did Europeans feel it was their duty to colonize African countries?

answer:

The reasons for African colonization were mainly economic, political and religious. ... These countries became involved in a race to acquire more territory on the African continent, but this race was open to all European countries. Britain had had some success in halting the slave trade around the shores of Africa.
