How did European countries attempt to profit from the African colonies after world war 1?

After World War I, European countries sought to profit from African colonies primarily through the extraction of Natural Resources, such as minerals, rubber, and agricultural products. They implemented exploitative economic systems, including cash crop farming and forced labor, to maximize production and export profits. Additionally, colonial governments built infrastructure, like railroads and ports, to facilitate the extraction and transportation of resources, further integrating African economies into global markets dominated by European powers. This exploitation often disregarded the well-being of local populations and led to significant social and economic challenges in the colonies.
