Which European motive behind imperalism in Africa was the most powerful?

The most powerful European motive behind Imperialism in Africa was economic exploitation. Colonizers sought to access and control Africa's vast Natural Resources, including minerals, rubber, and agricultural products, to fuel their industrial economies and enhance their wealth. This economic drive was often accompanied by a belief in racial superiority and a desire to spread Western civilization, but the primary impetus remained the pursuit of profit through resource extraction and market expansion.
