Which of the following African countries was most successful in resisting colonization?

Ethiopia was most successful in resisting colonization because it was able to maintain its independence and sovereignty throughout the colonial period. Unlike many other African countries, Ethiopia successfully defeated several attempted invasions by European powers, most notably Italy during the First Italo-Ethiopian War in 1896 and the Second Italo-Ethiopian War in 1935-1936. Emperor Menelik II played a crucial role in modernizing Ethiopia's military and diplomatic strategies, which significantly contributed to the success in resisting colonization. The Battle of Adwa, where Ethiopian forces defeated the Italian army, is considered a significant turning point in world history, as it demonstrated to other African nations they could resist European colonialism.
