Basically a WW2 ATL (or post WW2? Well the change from main TL is TTL's WW2 at any rate) from my "The Kaiser, the Tsar, and a Springtime Revolution". One of three scenarios I had about that TLs WW2 going differently. This shows the Anglo-Britannic and Anglo-Indian wars ending with British (Anglo) victory, which leads to US and Mexico later defeating Socialist Central America and there being no intervention to save Socialist Uruguay and Paraguay from Argentina. Allied Powers of Germany, Russia and Italy were defeated by the Latin Entente (only thing that makes that name inaccurate is South Slavia and later Finland). This is the immediate post war world where decolonization could not happen yet. Now getting to notes:
1: French State is victorious, that much is certain. And as such a scion of House of Orleans now sits in Paris. Jean, Duke of Guise might not have been crowned but now that Germany and Russia have been defeated Regent Charles Maurras has finally managed to get the Count of Paris to be crowned Henri VI, King of the French.
2: The House of Lords, the Legitimate House of Commons (now no longer in exile), and King Edward are all in a very celebratory mood now that Union of Britannic Syndicalist Commonwealths is defeated. Otherwise rebuilding continues. The Kaiser and the Tsar might have been their enemies but they were still family to the house of Windsor. Also an Orleans might be reigning in Paris but His Majesty's Government finds it hard to not see Napoleon and his continental system. Safe to say the Foreign Office is working hard to gather allies so that France's domination of the continent will not last.
3: Unsurprisingly, France did not let Germany stay united. But with Action Française in power they are still monarchies. Dutch, Saxon, Bavarian and Liechtenstein monarchies remain, While in Brandenburg Wilhelm III had to abdicate but Hohenzollerns kept the throne. House of Hanover is pretty thankful for their "Westphalia" while in Bohemia the Romanov king has been replaced by a Czech aristocrat.
4: In Italy France has tolerated 3 Republics however (Switzerland also remains a republic). House of Savoy also got to keep Piedmont. Italy also shows some of the gifts Spain has gained. Naples is a Spanish puppet under House of Bourbon-Two Sicilies.
5: Neutrality in both World Wars has helped the Ottoman Empire much. The House of Osman now reigns over an Empire that rivals France and Britain in strength. Its late declaration of war on Russia was an opportunistic move to secure Caucasia and "liberate" Turkestan. The Sultan-Caliph has invited the King-Emperor and the Tenno (with their Prime Ministers) to hash out a treaty that will make the anti "Latin" Entente alliance that is tentatively called London-Constantinople-Tokyo Axis (shame that League of Three Emperors had already been used).
6: Russian Republic or West Russia. Eastern Europe is weirdly republican when you consider that they are satellites of the Actionist France. New government in Petrograd is appropriately Religious, Nationalistic and Anti-Semitic for Paris' tastes however.
7: Indian Republic invading the remnants of the Raj during their war with UBSC was first seen as bad in Ottawa. But they managed to defeat them and restore the Raj to how it used to be, so London is fine with it. That war would eventually happen so it is all well that it was handled sooner.
8: China can be considered the beating hearth of socialism. How long that hearth will continue to beat is debatable however.
9: France gave Spain a few more prizes in the form of colonies. Regent Francisco Franco was forced to crown the Legitimist Pretender to France (under the name Henry VI) and (unpopular among Carlists, who had fractured in 1936) Carlist claimant to Spain, Jaime Bourbon as King of Spain. This was mostly Maurras throwing a bone at the Legitimists. Like Maurras, Franco did not cede any power to the newly crowned King.
10: The Empire had to give most of Africa, Ceylon and Burma dominion status to keep them without rebellions. The areas reclaimed from UBSC are not going to get that status as long as His Majesty's Government can help it.
11: A Romanov reigns in Vladivostok. The Tsar and his ministers often ponder about whether losing European Russia or becoming a puppet to Japan of all nations is more embarrassing.
12: Mexico is quite happy with their alliance with the US and their gains from the war against socialists. "The Perfect Dictatorship" is quite content with its circumstances. Some consider abandoning US to join up with the Entente however. (The fact that this might lead to US joining with Britain-Ottomans-Japan is mostly ignored)
13: Argentina is quite close with UK and will likely remain so. the, Entente member, Integralist Estado Novo Brazil is a much bigger issue than Malvinas after all.
14 (not on map): Nuclear Weapon hasn't been invented yet but France, Brazil, Britain, Japan and Ottoman Empire all have programs at various levels of advancement.
