Just skimming Wikipedia for a minute :

"The cotton gin was invented by Eli Whitney in 1793 and served to reinvigorate the slave economy in the United States, adding decades to its life."

"In Europe and then in the young United States, inland canals preceded the development of railroads during the earliest phase of the Industrial Revolution; some canals were later drained and used as railroad rights-of-way. Navigable canals reached into previously isolated areas and brought them in touch with the world economy. The Erie Canal, for instance, opened up a connection from the populated Northeast to the fertile Great Plains."

"The development of the railroad in the United States helped reduce transportation time and cost, which allowed migration towards the west. Railroads increased the accessibility of goods to consumers, thus allowing individuals and capital to flow westward."

"The area claimed by the Confederate States of America was overwhelmingly rural. Small towns of more than 1,000 were few — the typical county seat had a population of less than 500 people. Cities were rare. New Orleans was the only Southern city in the list of top 10 largest U.S. cities in the 1860 census."

"The Confederacy had an agrarian economy with exports, to a world market, of cotton, and, to a lesser extent, tobacco and sugarcane. Local food production included grains, hogs, cattle, and gardens. The 11 states produced $155 million in manufactured goods in 1860, chiefly from local grist mills, and lumber, processed tobacco, cotton goods and naval stores such as turpentine."

"The Act Prohibiting Importation of Slaves of 1807 is a United States federal law that stated, in accordance with the Constitution of the United States, that no new slaves were permitted to be imported into the United States. This act effectively ended the legal transatlantic slave trade. However, slavery continued in the United States until the end of the Civil War and the adoption of the 13th Amendment to the Constitution."
