The person known as the "Napoleon of West Africa" was Samori Toure. He was a military leader and founder of the Wassoulou Empire, which covered parts of modern-day Guinea, Mali, Ivory Coast, and Senegal.
Toure was known for his military strategy, which allowed him to resist French colonial expansion in the late 19th century. He established a strong centralized government and a professional army, which were equipped with modern weapons and trained in modern tactics.
Toure's military campaigns were characterized by his ability to mobilize large numbers of troops and to adapt to changing circumstances. He used a combination of guerrilla tactics, fortifications, and traditional warfare to defeat his enemies.
Despite his military success, Toure was eventually captured by the French in 1898 and exiled to Gabon, where he died in 1900. His legacy, however, lived on, and he is still remembered today as one of the greatest military leaders in West African history.
