The Nubians were from southern Sudan later called Kush. no one knows when they arrived there. they grazed on savannas. They were good at growing crops and they were good at hunting. They were pretty much known for their fighting skills. They also took over the weaker Nubians and created a kingdom that is now called Kerma .
Since iron tools were different and a ton more powerful than what the other communities had, the iron tools and weapons made the Kush Nubians one step ahead of everyone else. They had the top notch weapons, which was so much better than what everyone else had, the farmers from Kush also used it for better farming material
They imported and exported from each other.
