... marshal law was declared in several southern states and the state governments replaced in order to get ratification...
This is getting off topic but I will post on it to play along.
Not exactly so. The Reconstruction Act of 1867 abolished civilian governments in the former Confiderate States and to be readmitted to the Union that Lincoln said that they had never left they had to radiffy Amendments 13, 14, and 15 as a condition of readmidance..
Political Correctness is our greatest danger. This is so because Political Correctness is blind to the duel threat posed by Siera Law and La Raza. Both of these threats are much more serious to the future or long term survival of America than slavery ever was.
By 1850 the economic dislocation posed by the Industrial Revolution coupled with a fast growing world population , numbered slavery's days. However slavery and its economic impact was the core issue that deepened geographic as well as economic differences and these deeping rifts led to a national split. However if slavery ever stages a come back in North America it will be because of something like sustainable, organic, local-vor agriculture and its need for gobs and gobs of cheap hand labor at the drop of a hat.
In 1860 the Democrat Party was the party of free trade, and the Republican Party was the party of high tariffs. The South wanted to trade freely with the world, exporting its raw materials like cotton, corn, timber, and tobacco, (before the Civil war more corn was exported from Charlston, South Carolina than from anyother American port) and using the profits of this trade to buy cheaper and better quality goods than were generally available from the Northern factories of the day.
The American merchant marine infact has never overcome the tripple hits of ships lost to Confederate raiders, the flight of US vessels to forigen flags because of high insurance rates caused by these raiders, and the decreased international trade to American ports caused by higher tariffs in the aftermath of a Northern victory.
This was basally the dynamic that caused George Washington and most of the founders to turn their backs on England. The Brittish were taking her North American colonial consumers for granted, by forcing ever lower prices on us for colonial products inforced by banning world trade with the colonies, while charging us ever higher prices for ever shoddier English goods.
GM, Chrysler, as well as Rambler, Packard, Nash, Willis, and a host of other brands and manufactures met their end the same way. That way is the way of the market, and among other things the market led to China loosing her tea monoply while the Brittish fretted over the ongoing slave trade in Cuba, Egypt, Nigeria, The Soudan, and Kenya on the one hand while with their other left hand the English profited greatly from the trade in Indian (Afghan Pakistan) opium for Chinese tea. The English even fought several wars with China to get or keep their street corner location to better smuggle Afghan opium into China. Meanwhile the English fought two disastrous (Disastrous at least for the English) wars to safeguard their supply of Afghan opium.
Another example is Brittan using armed force into the 1940s to force India to pay dearly for English salt and cloth even though India is situated between two great oceans chocked full of salt and historically India was both a grower of cotton as well as a center of spinning and textile weaving. How many Indian (Hindu) fabrics can you name?
The Northern Republicans wanted more internal trade and high taxes on imports to both ensure profits for factory owners as well as to protect factory workers jobs. Then like now a rising economy floated all boats. Marx more than once said that the only thing the American Worker wanted was to get rich, if not to actually become a Capitalist himself. Even though Marx and Engels Together wrote more than 300 articles for Republican Newspapers, neither one was optimistic about Socialism taking root in America.
Today every time someone mentions "Cheep Chinese" goods or "adulterated imported honey" or "buy American," I bet you can scratch that person and you will most likely find a Classical Republican under the surfice. If on the other hand you are driving an imported car (especially a hybrid or up scale brand like Mercedes, SAAB, BMW, Jag, Lexus, etc) you are more likely a Classical free trade Confederate.
