Step-by-step explanation:
Most Sub-Saharan African countries gained independence in the mid-20th century, with the transition from colonies to independent nations often resulting in conflict. The first country to gain independence was Ghana in 1957. This pattern of decolonization became common after World War II and paved the way for independence movements throughout the continent, which were frequently met with civil wars and political chaos as they transitioned to self-governance. Despite the challenges of political restructuring and economic development, some countries have since succeeded in establishing stronger political structures and greater democratic liberties.
