What always happens to a nation that begins, grows and then declines? The people become arrogant, greedy, and a belief in their manifest destiny takes over. America began with a desire for freedom from the oppressive king and Church of England. The moral differences were secondary and each state was to be allowed to decide what went on within their borders (IE: states’ rights). Slavery in the southern colonies was looked down upon in the northern colonies even though they too had slaves. The first slaves in the colonies were white, and often called “indentured servants.” In 1519, the first black slaves landed in North America. They were captured by black and white, and Arab (Muslim) slavers. The southern states’ economy was dependent upon slave labor. As territory was added to the U.S., another compromise was put in place: the Mason-Dixon Line. North of that line were called free states, below it were slave states. This did not resolve the slavery issue. It merely postponed it.
At this point I want to stress that white Americans did not invent slavery or bring slaves into North America. Britain, France and Spain brought slaves to our shores. By 1770, six years before the Declaration of Independence, there were approximately 50,000 slaves in North America, both black and white. What happened next?
