What were the two biggest european motives for imperialism (in africa)?

One strong motive was mainly economic: the desired control of lands rich in resources and raw materials for the industrial economies of Europe; Europeans wanted to exploit them and saw the native populations as a source of forced or cheap labor; they also wanted new markets for their industrial products. Another important reason for European colonial and imperialist expansion was prestige; possesing colonies was seen a symbol of the status of great power.
