Introduction During the early national period, slavery was as normal as breathing. It was legal, popular and was expanding every day. In his book, “ American expansion and the origins of Deep South ”, Adam Rothman argues that we must understand the origin of the Deep South if we are to understand the expansion of slavery during the early national period. It is a fact that slavery was becoming more acceptable because in the southern states, the number of slaves was growing bigger. More slaves meant more manpower hence development of Southern economies would accelerate ahead of the rest. A good percentage of every household ensured they have a slave. The slaves themselves were reproducing naturally. This means their numbers over the years were increasing more than the rate of importation of new slaves from Africa. It was hard controlling the growing population, especially taking into account that the slaves were contributing massively to the then required rapid growth in the economy. An attempt to reverse the status quo would equally reverse the economic gains achieved over time by for example reducing the amount of export. Development of Economies of Deep South In North America however, most of whites were opposed to slavery even though they wanted them to be given their own freedom where they lived. But in the southern states, those who owned slaves were a respected lot since they had acquired a lot of property, thanks to the free labor that was readily available. In the North, the few slave owners only gained by having free transport of their agricultural products to markets abroad. As elites and politicians continued to criticize slave trade, Southerners who benefited from slave trade had their economies growing fast, hence the development of famous states such as Louisiana, Alabama and Mississippi (Rothman 6) In South Carolina and Georgia for example, the beneficiaries of slave trade strongly defended slavery. Political debates over the abolition of slave trade led to other states threatening to withdraw from the union, especially by the delegates from the Deep South. They not only hated the idea of emancipating slaves but also argued strongly that if given freedom, they were doomed to fail. In the upper South, those who owned slaves were for the idea of stopping importation of more slaves since their population was already increasing yet those in the lower South did not hold a similar view. So the Deep South continued to benefit from free labor offered by the slaves and developed a stronger economy than the rest of the States (Rothman 13). War and Growth of Deep South Following sustained wars that prompted the expansion of the geographical frontiers of the North America, the Deep South (the present states of Louisiana, Alabama and Mississippi) was accommodated into being part of the United States since they had a larger and more powerful economy. Availability of good agricultural land, opportunity to get rich plus ready free labor made the Deep South gain more status and reputation among the other states. There was expansion of trade, improved livelihood and renewed hopes and all this was attributed to expansion of slavery. In fact at some point, whites in are
