It was a war between the states, the south did not want the north to tell them what to do. it started when the south wanted to sell Cotton and other supplies to england,but the North said no you can"T they wanted to buy it at a much cheaper price, the slave issue was much later, when early explorers found places such as africa they observed and meet tribes raiding and conquering other tribes and enslaving the captures,the better tribe talked,and gave the early explorers[example the dutch]and others the idea of having slaves, tell the truth about history ,don"T lie just to sugar coat it just to be political correct, that is one of many reasons this country is going down,taking GOD out and all, glad I am not an american
