Who was the head of the Zulus at the time of the Mfecane war?

The head of the Zulus at the time of the Mfecane war was Shaka. Shaka was a powerful leader who rose to power in the early 19th century and established the Zulu kingdom in southern Africa. He was known for his military tactics, which were innovative for the time and allowed him to conquer many neighboring tribes and establish the Zulu kingdom as a dominant power in the region. The Mfecane war, which took place between 1815 and 1840, was a period of intense conflict and migration in southern Africa, largely caused by Shaka's expansion of the Zulu kingdom.
