The correct answer is that the Bantu were among the first to use iron, especially when it came to the construction of weaponry that gave them an edge over other tribes in Africa.

Explanation:

The Bantu tribes are a group of people from Africa, whose origins are unknown. They became one of the best organized and most powerful of the tribes that inhabited Africa and they extended from East to South Africa. Initially known as West Africans, this group of people began migrating slowly, in small groups, between 1000 and 1800 A.D, in search of more, and more fertile, lands for inhabitation and agriculture, for their increasing numbers. Later on they acquired the name Bantu, which means "The People". Around 400 A.D, the Bantu were able to expand faster, and be successful against more hostile tribes, due to the fact that they began developing iron weaponry, which gave them an edge. Afterwards, the Bantu began also utilizing iron to create farming tools and other technologies, which made them powerful and advanced.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
