Final answer:
Post-WWII, the inability of France and Great Britain to maintain their African colonies was influenced by the exploitation of resources, denial of political rights, and the principle of self-determination strengthened by African participation in the war.
Step-by-step explanation:
By the end of World War II, France and Great Britain had claimed the majority of all land and resources on the African continent. However, they were unable to maintain control over their African colonies post-war due to several factors. The blatant exploitation of resources, denial of political rights to African people, and emphasis on colonial powers profiting at the expense of local populations caused widespread dissatisfaction. The mobilization of African communities during WWII and their significant contribution to the war effort sowed the seeds for self-determination and the questioning of colonial rule. Moreover, the haphazard division of territories without regard for ethnic or cultural lines during the colonial period led to internal conflicts that undermined European control.
The struggle for independence was propelled by the realization of African soldiers and citizens that the principles of self-determination applied to them too, especially after their substantial participation in both World Wars. Increased globalization and exposure to international ideals made the colonial model appear outdated and unjust. Post-war, existing economic pressures and changing global attitudes towards colonialism also played a role in the decline of European empires in Africa.
