What mistakes did Europeans make when they colonized Africa?

Europeans made several critical mistakes when colonizing Africa, including a lack of understanding of the continent's diverse cultures, languages, and social systems. They often imposed arbitrary borders that disregarded ethnic and tribal affiliations, leading to long-term conflicts. Additionally, the exploitative nature of colonial rule disrupted local economies and ecosystems, resulting in lasting negative impacts on African societies. These missteps contributed to instability and challenges that many African nations continue to face today.
