Mongols rule OK!
It is largely true in my opinion.
I would add that the Mongols successfully invade southern China and the far north of Vietnam as in reality, then most of what is our Vietnam, but they don't like the heat and get out.
Spain and Portugal just stopped the Mongols at the Pyrenees. Scandinavia survived and got Denmark back after a while. Malta, Tunisia, Sicily, Corsica and Sardinia hods out for a longer time.
The Mongols push on deeper into the Indian subcontinent. The Punjab and Mongols clash in the 18th and 19th century.
Morocco and the Algerian Barbary Coast hold on until much later (OTL conquered 1830-1905).
British USA
It is largely true in my opinion.
The map of the British Empire was slightly wong. Origin would not have been divided with the USA, but apparently Spain. In my opinion the UK tells Spain to bugger off and we have a war. There were only a few Spaniards in that zone when they OTL had it. The UK takes it easily, stopping at the Sacramento area.
Napoleon becomes the head of the Royal French Army, takes power in a coup and is finally removed in favor of the king. The 1805-1015 War of Louisiana takes place, thus giving it a date later than depicted (the picture is of Hanoverians).
The Communards are crushed in the Paris Commune.
John D. Rockefeller's North American Imperial Oil Company is created 1870 and quite literally fuels the British Empire.
Serbians nationalism causes the Austro Hungarian-Serbian war of 1914-1916, but the Serbs are quickly crushed by the British and Greece is bolstered by the British.
The Bolsheviks come to power in Russia.
America becomes a Dominion and then fully independent at the same time Canada dose.
The Great Depression is an ideal tool for the anti-Semitic Austrian corporal Adolf Hitler to use rise to power in Germany, but Europeans defeat Germany in the 1936-1939 German-Austrian War.

Serbians nationalism causes the First World War.
The Bolsheviks come to power in Russia.
The Great Depression is an ideal tool for the anti-Semitic Austrian corporal Adolf Hitler to use rise to power in Germany and he causes World War 2. Anti-Monarchist/Marxist riots are suppressed in America's cities.
America is even more anti-Communist.
The Monarch is restricted by law as in the UK, but has so much (mostly doubius land ownership) wealth that it can even buy off Bill Gates.
CSA wins
.I agree with most of it.
Texas gets independence in 1991 after the cold war fades and it feels free to go it's own way. It then loses the 1991-1995 Texan war of Independence and is re-annexed to the USA in 1995, with reconstruction and martial law ending in 2008.
