Elisabetta Farnese is pretty unlikely under this scenario, maybe Philip will marry an Austrian Archduchess in the peace treaty? Joseph I’s eldest daughter Maria Josepha would be 14 years old, his youngest sister Maria Magdalena (who in OTL was proposed as second wife for Philip) 24 years old...In alternate timeline where Philip of Anjou becomes heir to the French throne in 1712 due to his brother and nephews all dying (instead of his brother and elder nephew dying while OTL's Louis XV survives) but where there is still seen within France a possibility to win Spain (which realistically is lost) and his first wife, Maria Luisa of Savoy, still dies in 1714, who does Philip of Anjou marry? Is Elisabeth Farnese still on the table or is it preferable for Philip to marry someone else?
thats not dissimilar to what happened IOTL. With Rome passing its authority to Constantinople, which in turn passed its authority down to the Russians. Although this was more in the eyes of the Russians themselves. But there is an OTL precedence of sorts for this kind of thing.I had a fairly frivolous idea about a "migrating" Roman Empire: After the fall of Rome, Byzantium conquers the Sassanid Empire. The Byzantium-Sassanid Empire then loses its European, Anatolian, and North African territories but conquers Sind and Gurjara in northern India. A butterfly net protects the rise of Islam and so the non-Indian parts of the Empire are eaten by the Caliphate. *Gurjara conquers all of northern India. So on and so forth until in the modern daythere's a state in southeast Asia that can trace itself in an unbroken line back to Rome.
I actually have something like that happen in my timeline "Jefferson's Anti-Slavery Crisis". The Southron Rebellion occurs because of something very similar (southern colonies formed when GA, NC, SC leave US at Continental Congress; this rebellion is quashed). Is "civil war" still the right term though? I feel like this is more rebellion or attempted independence war or colonial war if this is a British America we're talking about, though.British America still has a Civil War, after Queen Victoria orders the 1833 anti-slavery act be enforced in the southern provinces.
