Don't blue ball us like that, post em.
In very brief form -
* the CSA wins independence by an incredible fluke of luck. Which is the only way it could win.
* Flush with ill deserved victory, the Confederacy launches an invasion of Cuba as its next target for expansion, which fails spectacularly as the Spanish kick its ass. Spain was still a modern naval power in the 1870's and the Confederacy was definitely not. A Confederate Army which manages to make a landing on Cuba finds it self surrounded by hostile Cubans who discover a new Spanish loyalism, after making enemies of the population, the Confederate army is horrifically but slowly obliterated. The Spanish navy bombards the Confederate coasts, including New Orleans, with impunity. A Spanish occupation of South Florida follows. The Confederacy sues for peace, North Florida leaves the Confederacy and enters into a loose affiliation with England.
* Meanwhile, the Confederacy turns west, seeking to expand by occupying Northern Mexico with the aid of local allies, to the extreme displeasure of the United States, France and Mexico itself. The Confederate military governance, with inadequate logistical support from home, supports itself with brutal forced labour and confiscations from the local population, earning undying enmity and further blackening the reputation of the Confederacy worldwide. This results in an increasingly ferocious guerilla campaign and eventually an outright war with Mexico. Defeated the Confederacy is forced to withdraw and even cede pieces of Texas.
* The Texans, feeling that they were made to bear the brunt of the costs and manpower levies of the war with Mexico, and forced to assume the territorial losses, and blaming the rest of the Confederacy and its lack of support (the old 'stabbed in the back' myth), decides to leave the Confederacy... Which results in the Texas Confederacy war, and the second devastation of New Orleans. The Confederacy loses, of course.
* Reunification negotiations with the Union fall apart, leaving Northern Texas seceding a la West Virginia and going off with America. The end result is a Free Texas with both its south and north chewed away, diminished, wartorn, bankrupt and without the support and trade of the rest of the United States, it more or less fades from history as a shabby little backwater, passionately loathed by both the Mexicans and Louisianans, and forgotten and ignored by everyone else.
* The Confederacy, in financial ruins from losing three consecutive wars, retreats into a state of denial, as the landed gentry continue to consolidate wealth and power. The war costs are repeatedly addressed by printing more currency, leading to bouts of hyperinflation and currency crashes. Hence, most of the Confederate well to do prefer to put their wealth into land and slaves, principally nonfungible commodities. The Confederacy fails to develop anything resembling a financial infrastructure. This is compounded by dissension and distrust among the states.
* Nevertheless, the Confederacy, or fire breathing elements therein, continue to embroil it in messy foreign adventures or filibusters. There's a disastrous intervention in the Yucatan, Filibusters attempts in Haiti, Nicaragua, and Costa Rica, unpleasant and humiliating confrontations with the British, French and even the Dutch navy.
* With a massive shortage of liquid internal capital, a decided lack of foreign investment, a largely bankrupt and incompetent Confederate government, quarreling states and a constitutional prohibition against infrastructure projects - the Confederacy fails to build, or even maintain its infrastructure. Confederate internal transportation is a rickety and unreliable patchwork of failing rails, bad roads, navigable stretches of river, and avaricious local barons and bandits The Confederate economy is rife with systemic inefficiencies that it fails to address and worsen steadily. The standard of living declines steadily in most of the states. The rich hedge their bets by keeping their money in slaves.
* The Confederacy steadily degenerates into essentially a single cash crop neocolonial economy. Those who control or are involved in the cotton trade prosper. Everyone else, fails to do so. Unable to build or maintain infrastructure, foreign nations, chiefly the United States and Britain, but also France, Germany, Holland and even Belgium obtain local concessions, maintain, own and operate facilities. The Confederate ruling classes spends its moneys on imported luxuries rather than indigenous development.
* Despite all that, a small middle class develops in several coastal cities, and Birmingham emerges for a time as an Industrial center, based principally on access to coal and iron ore, and taking advantage of new developments in Iron and steel production which leave it temporarily ahead of its American and British rivals and their older industrial plant. However, lack of economies of scale, a small internal market, fierce external competition, eventually chokes off the Confederate steel industry and it too fades away.
* The only bright spot is Louisiana and New Orleans - prosperous as a trading nexus, sophisticated, urbane, multi-cultural and multi-racial, New Orleans tariffs are a critical pillar of the Confederate finances.... In return for which, Louisiana gets nothing whatsoever.
* Louisiana decides to withdraw from the Confederacy, triggering a Confederate invasion and occupation. However the French, Americans, British and even the Texans intervene decisively against the Confederacy, triggering yet another military disaster. Kansas is lost to the United States, and humiliating terms and penalties are imposed.
* Meanwhile, the wealthy, continuing to consolidate their investments in slaves, with no one to sell their slaves to except each other, have been slowly mounting a 'slave bubble' in which the paper value of slaves is dozens of orders of magnitude in excess of productivity. The Louisiana defeat triggers another familiar bout of hyperinflation, which drives up the value of slaves as a 'refuge for wealth', which then triggers the bust of the slave bubble.
* Overnight, fortunes everywhere are obliterated, followed by the collapse of a landholder based economy. The dependent middle class is devastated, schools and public institutions are closed or abandoned. Destitute planters simply abandon their slaves or drive them out into the world. This leads to runaway social crises, including local uprisings, genocides, atrocities of every sort, starvation, mass movements of population.
* In an effort to stabilize the situation, the Confederate and State Governments assume ownership of all abandoned slaves. Many are euthanized. Many are worked to death in forced labour. Most are rented back to their former owners under horrific conditions.
* In an effort to maintain economic function, the Confederacy becomes a command economy. However, cash strapped, its power devolves to local states, municipalities and particularly strongmen. The Confederacy degenerates into a morass combining the worst aspects of feudalism and communism. Standards of living continue to decline, local starvation is common, local epidemics are untreated, literacy rates among whites are around 5%. Surviving confederate elites operate through a combination of theft and brutality.
* Obviously, the hellholishness is not universal. Some areas and states, particularly coastal ones, maintain order and civilization. Some states, particularly 'Less Virginia' have had enough, and petition to rejoin the United States. America is less than welcoming however, the negotiations founder on the issue of slavery. Later, the United States refuses to consider any further overtures to rejoin.
* With nowhere to go, with critical sources of revenue lost, the Confederacy is poorly prepared for the boll weevil. Again, there is massive state confiscation of abandoned slaves, euthanasia, slave rebellions and race riots. With the final progressive collapse of the cotton trade, the Confederacy continues to degenerate - conflicts between different states result in the Confederacy being sundered into two or three warring successor states. Power devolves to counties, with powerful counties ruling their states. Conflicts between powerful counties result in territory being fought back and forth, groups of small counties being consolidated into new puppet states. The remaining seven states of the original Confederacy being divided into a motley assembly of some thirty warring and competing petty microstates, fiefdoms and badlands. A region of incredible grinding policy, ruled by savage tyrannical elites who maintain their position through pseudolegal theft and relentless brutality, with a standard of living an average Haitian or a poorer African would consider degenerate.
That's basically what I have in mind. Except, you know, I plan to make it ugly.
