I'm going to differ with you on your third presupposition, in that I believe a surviving CSA is likely to take a massive swing to the Left by the early 20th century - precisely because the levels of wealth disparity caused by a slave-holder system would be totally unsustainable. The concept of the 'American Dream' is much weaker OTL in the South, and I believe political separation from the North will be enough to kill it completely - Confederate citizens will not believe the myth that the new world is a land of opportunity, where anyone who works hard can achieve prosperity; but rather they will see their country for what it is, a land where classism and economic oppression are rife.
And so, by the 1910s-20s, there will be a social democratic revolution, overthrowing the old landed élites, and installing a government of Poor Whites and Blacks. Meanwhile, the old élites flee up North and rebrand themselves to fit in with the Yankee aristocracy. The post-Revolutionary CSA definitely has at least one Black president before 1950.
So the history textbooks mandated by the Confederate Department of Education will probably have a nuanced take on the Confederate War of Independence. On the one hand, those who fought for independence were their enemies in the later revolution, but on the other hand, without their contribution, independence would have never been possibility. Confederate historians would emphasise that their nation is one with a dark past, but a bright future.
A possible table of contents for a Confederate history textbook:
Ch 1. Pre-Columbian peoples.
- This chapter would celebrate the indigenous inhabitants of the CSA, pointing out where applicable that the modes of social organisation of these peoples was far more egalitarian than anything practised in contemporary Europe.
Ch 2. Ancient Europe.
- A quick potted history of Ancient Greece and the Roman Empire.
Ch 3. Columbus and the Slave Trade.
- The discovery of the Americas and the near-immediate introduction of chattel slavery are taught as two sides of the same coin.
Ch 4. Pre-colonial African History.
- A quick look at the societies from which African Confederates were extracted from. Including the history of Islam in Africa.
Ch 5. The American War of Independence.
- This topic is taught much more open-endedly in the CSA than in the Union, (where the WoI is unanimously considered a victory for enlightenment values over arbitrary state power). Confederate schools teach that while there was certainly a lot of idealism among the Patriots, the baser motives of the Founding Fathers are also considered, (i.e. monetary greed, desire to encroach further into Indian lands), and the fact is taught that despite the high-minded principles of the Patriots, slavery was allowed to continue and women and the poor were disenfranchised.
Ch 6. Slavery and Economic Exploitation.
- This chapter is essentially a socialist political-economic critique of American expansion. The evils of this era are blamed strongly on the Northerners and the Southern élites.
Ch 7. The War of Confederate Independence.
- Both sides are criticised. The South for their immoral insistence upon protecting the institution of slavery, and the North for their greed, hypocrisy and trigger-happiness. However, individual acts of braveness from working class Black and White Confederate soldiers are applauded.
Ch 8. The Causes of the Confederate Revolution.
- It is emphasised that the CSA as it stood on the dawn of independence, heavily indebted to European powers, economically ruined, and with a generation of widows, orphans and war-wounded was almost immediately on a path to revolution. It is explained that the introduction of racially-integrated regiments towards the end of the War had a great deal to do with the formation of the Poor White/Ex-Slave Black coalition that would later seize control of the nation. The events of the revolution and its immediate aftermath are also covered.
Ch 9. The Global Revolution and the First Great War.
- The textbook again revisits the world outside of the Americas, describing the events that led to the successful socialist revolutions in Germany, Spain, Italy, Egypt, and Japan. The First Great War is described as a conflict between these socialist powers and the parasitical imperialist powers of Britain, France, Russia, and the USA. The hardships of the Confederate home front, the constant threat of invasion from the North, and the proxy war in Mexico are taught in this chapter.
Ch 10. The Inter-War Period, Second Great War and Decolonisation.
- Explores the massive economic strife experienced in this time, and the rise of Right-wing extemism. The Second Great War is portrayed as being humanity's lowest point, with heinous war crimes committed on all sides, leading only to bloody stalemate, culminating in the Deutsche Volksreich's atomic attacks against Britain and France. Attention is paid to the forced dismantlement of the British and French Empires and the establishment of the Permanent International.
Ch 11. The Confederate Golden Age.
- Explores how society changed after the end of the War, as new found peace, prosperity, and personal liberty were enjoyed by the CSA and its citizens. Key points include the broadening of the welfare state, the ascension of the new Caribbean states, and the conclusion of the non-aggression treaty with the Union.
Ch 12. The Communication Age and Cosmopolity.
- Describes how the introduction of new technologies have brought the world closer together, and greatly reduced the chance of a new Great War. Also asks students to consider how such trends may effect the future, specifically whether the traditional socialist ethos can survive cosmopolity, (i.e. globalisation), in tact.
