Answer :
the tradition that the Batu brought with them throughout their migrations is farming
Answer: Farming
During the Bantu Expansion, the Bantu people spread from West Africa and Central Africa across much of sub-Saharan Africa. The expansion is believed to have been caused by the development of agriculture, which the Bantu carried with them. This allowed them to displace or absorb pre-existing hunter-gatherer and pastoralist groups in these areas. Bantu people also exceeded in the making of ceramics and the use of iron.
