I think, I'll just do a Wall 'o' Text to fully explain my map.
North America
The United States doesn't practise slavery, the peculiar institution having faded away by the time it was abolished in the 1870s. So no civil war. Since France put more effort in Louisisana (just a general trend, no POD) and the Ohio Country was still British, the only avenue for American expansion was into Africa, first in Liberia and then in New Washington (Namibia). America is very stratified racially with many layers according to mixing, but the colonies are far more egalitarian with whites and blacks mixing freely.
Florida is a bit like Texas. It gained independence from Spain with American migrants leading the way. However, the American refusal to admit a new state into the union lead to a short war in which the Floridians received aid from Britain. The Floridians practised slavery up until the 1880s when the slaves rose up and tried to overturn the slavers. The slavers won, but slavery was quickly abolished and the slaves repatriated to New Washington.
The British colonies are still largely governed by the Hudsons Bay Company, at least officially. However, by now the Proprietors of the Company are elected by the people of Rupertsland and come from the vast territory. The Metis-Scots mix of people who form the nation along with the many native peoples are unwilling at the moment to alter the status quo fearing that competition with the HBC would lead to an erosion of their traditional lifestyle.
The United Kingdom of Canada is mostly French-speaking, though there is a significant Irish population in Upper Canada. With control over pretty much everything except foreign policy, the Canadans (no spelling mistakes) are happy with their lot. Much of the population are decended from Catholic dissenters and people unhappy with the constitutional monarchy after the Great French Reform.
Newfoundland, Labrador and Baffin are fully integrated into the United Kingdom, after the largely British-Irish-Danish population didn't want to be annexed to Francophone Canada. Some of the population call for a United Kingdom of Newfoundland and Baffin, but they are marginalised by those who feel that such a state could not stand up outside of the British state.
There are four crown colonies, Ohio, Charlottania, Nova Scotia and Prince Edward Island. Ohio and Charlottania are to all intents and purposes administered by Canada, and are given a very free reign hence the dominion colour. Nova Scotia and Prince Edward Island are in a state of flux unsure of which direction to take at the present time. Some want a Kingdom of the Maritimes, in all likelihood the most likely course. Some want to become a Province within Canada, an idea mostly voiced by the Acadiennes of Nova Scotia. Some even call for a direct annexation to Britain like Newfoundland, but this is unlikely considering the economic strength of the colonies.
The British colonies in the Caribbean look to be staying that way, with their economic production, cultural leanings and general importance to the British System of Trade.
Louisianne is the centre of the French Empire since the Great War in the 1920s. The colony had some success, with the help of Richelieu's Diocese System and the Mississippi Company's transplantation of French peasants. The Estates of the Ancien Regime were recreated in Louisianne, turning the colony into the most loyal colony in the whole Empire. Nobles emerged from explorers and land speculators, claiming for themselves titles like Comte d'Illinois and Chevalier de Shalage. The peasants worked on the plantations, administered by a civil service made up of Jesuit monasteries, and protected/enforced by native allies and auxiliaries. Though this system deteriorated due to distances, and became for more easy to move through, by the time of the Reform Louisanne was like a much emptier France. With the constitutional monarchy established, the Jesuit civil class was removed and a process of 'bourgeoisification' continued until only a remnant of the Ancien Regime remained in titled men and women and the divisions of the state known as diocese. Texas was annexed to Louisianne after French migrants rebelled against the Mexican authorities. Louisianne calls itself the Kingdom of the French and is currently deploying troops in France proper to conicide with the detioration in German hegemony.
Mexico is a highly centralised state, which reveres Santa Anna as the Father of the Nation. The atrocities and mistakes of his rule are only just being remembered, threatening the foundation of the entire state. However Mexico is one of the top economies in the world with a thriving chemical industry, and good relations with virtually all of its neighbours. Mexico is causing waves at the moment with its harbouring of members of the terrorist Black Fox organisation from California.
California is a reactionary, conservative state ruled by a council of Dons. Many Louisannais nobles fled to California and found themseleves integrated into the governing nobility. The Dons purchased their independence from Mexico using gold ostensibly from Spain, but really from California. Skirmishes occur regularly with their Mormon neighbours, as the Californians regard Deseret as a part of Alta California.
Central America has been pootling along quietly since its unification under Nicaragua, ruled by William Walker. Walker was the first of six Dictators of Central America, all of whom were Anglo-Americans. Until recently, the Constitution prohibited the abolition of slavery, put President Jorge de Sanchez agreed to call a new Constitutional Convention after large protests in every state, but most famously in Walker Square in the capital. The new constitution expanding the franchise and banning slavery is still being drawn up, but de Sanchez's decision has sparked the Latin Spring.
The Viceroyalty of Cippan encompasses all of Spain's remaining territory in America. Being a viceroyalty and very populous, Cippan has more than one seat on Spain's Central Junta and so forced Sapin to give Catalonia autonomy after the country was liberated from Germany's sphere. Cippan is mostly a mix of Spaniards, Catalans, former African slaves and natives.
Aloksu, Japan's only presence on a continent outside of Asia is composed of Daimyos along the coast, populated by Japanese, Chinese and Manchurians and the Interior, populated by natives, Japanetis (term of the Japanese answer to Metis) and some Russians.
I'll do some more tomorrow, gotta get off now.
