The famous leader of the Zulu nation known for his resistance against British colonization was Shaka Zulu. He reigned during the early 19th century and is credited with revolutionizing the Zulu military system and unifying various tribes under the Zulu kingdom. Shaka implemented innovative tactics and created a highly disciplined and organized army that effectively defended against colonial incursions. His leadership marked a significant period of resistance, particularly against British forces during the Anglo-Zulu War of 1879, despite the eventual defeat of the Zulu. His legacy continues to have a profound impact on Zulu culture and identity today.
