What was Shaka Zulu's military tactics and strategies?

Shaka Zulu, the renowned leader of the Zulu Kingdom in the early 19th century, revolutionized military tactics by introducing the "bullhorn" formation, which involved encircling enemies and attacking from multiple sides. He emphasized close combat with the use of shorter, stabbing spears called iklwa, which favored agility and speed over traditional long-range weapons. Shaka also implemented rigorous training and discipline among his warriors, fostering a strong sense of unity and loyalty. His innovative approaches significantly expanded the Zulu Kingdom and transformed regional power dynamics in Southern Africa.
