did chaka zulu conquer the ivory coast when he was alive?

Answer 1

"Shaka's kraal was located at Bulawayo (in modern Zimbabwe).
The mfecane, which means "crushing" in Bantu languages, began with the migrations of the northern Nguni, but was commonly associated with the military and socio-political activities of Shaka. These migrations ultimately spread through southern, central and east Africa."

Although the Bantus probably stated in a more northerly area, the Zulu and Nguni were primarily from southeast Africa. The Ivory Coast is on the west coast at the bottom of the hump that sticks out into the Atlantic. I don't think any Zulu ever went that far north. Chaka did conquer most of southern Africa, and his "empire" at its height encompassed some 200,000 square kilometers.

Answer 2

Little far north for that to happen.
