1792 - Fall
Western and Central England (now commonly referred to as "Mercia") - ERA stronghold
The ERA had finally managed to recover from the shambolic attempt to regain Liverpool from the retreating Irish in 1791 (which resulted in the burning of the city as well as the crippling of the ERA army). Had the ERA marched south in full force at the time, it is possible that they may have stolen a march on the Parliamentary forces of Yorkshire and seized London before the King could properly form his own forces. Instead, a bizarre three-way war would soon emerge destined to drag in the rest of Britain and, possibly, beyond.
The Republicans had done much damage to their own cause by the ill-fated attack on Liverpool. Perhaps worse, the constant infighting among the ERA factions would prove the government was not yet prepared to lead. While espousing universal suffrage, the fact was that no real votes had ever taken place. Factions of the ERA Parliament fought violently, often executing their foes when they gained the upper hand.
So chaotic was the Republican government that different juntas assumed control over military units. One would bizarrely raid west into Wales in hopes of finding support in the borderlands. This would be repulsed by the Duchy of Wales' troops allied with Irish regulars.
Faced with hunger after another failed harvest (and their greatest port city, Liverpool, in ashes) and no money to pay for it, the chaos continued.
Duchy of Wales
The Duke of Wales, German-born like the Duke of Cornwall, had arrived in the western Britain region with little expectation of remaining long. The French Government demanded monarchies and many expected that, one way or another, the Germans would be evicted. However, a generation later, both Wales and Cornwall retained their Germanic Dukes.
Unlike much of the rest of Britain, both Wales and Cornwall retained vestiges of the old Kingdom of Great Britain by possessing monarchs and Parliaments. In contrast, the Scottish "Republic", really just an oligarchy of powerful men, would never get around to selecting a King and allowed the ruling junta to continue in command. England, prior to the rebellion which broke it to pieces, had been dominated by the government of William IV whom ruled without Parliamentary approval.
Much had changed over the years in Wales. Throughout its long associated with England, Wales had come to be dominated by its larger, more populous neighbor culturally and politically. English became the language of the upper class and, increasingly, the border areas.
Among the first alterations made by the new Duke were the institution of Welsh as the language of government and education. This proved popular with the commoners whom would see a net increase in power due to the Welsh Parliament possessing no House of Lords (the nobles being seen as the true threat to the Duke). As education was expanded further and further throughout the realm, the Welsh language flowered culturally with new waves of poetry and Welsh identity-building. For the first time in two centuries, the majority of the middle and upper classes began to speak Welsh in large quantities rather than dismiss it as a "peasant's tongue".
The Celtic language would flower throughout the late 18th century and become the symbol of the independent people. When Britain fell to France in the previous war, most Welsh were dismayed to be informed that they were now independent. No one wanted to be dictated to by a foreign power. However, seeing the King of England dominating politically in contrast to the inclusive government of Wales (over 20% of adult males had the vote), this would lead to a growing level of popularity of the new Duke and of Wales as an independent nation.
Cornwall
The Duchy of Cornwall, like Wales, would slowly grow accustomed to independence. Unlike Wales, the Cornish language had been effectively dead for decades, known more among scholars than by commoners. Lightly populated Cornwall, bearing a mix of nobles and commoners in their unique Parliament, would approach France with requests for a guarantee of their sovereignty.
Grudgingly, King Louis XVI's ministers would agree to dispatch 2000 soldiers to Cornwall. This was not enough to protect the region from an encroaching army...but it did guarantee than any attack on Cornwall would be an attack on France. Too many Englishmen remembered the long decades of French occupation. Given their own problems, there would be few calls for England to invade Cornwall throughout the early 1790's.
Republic of Scotland
Having managed to gain independence for the first time in over a century, the nobles of Scotland formed a pseudo-Parliament...in which all the real power devolved to a handful of powerful men. In many ways, Scotland was no less authoritarian than England in 1792. Like in England, revolutionary fervor reached high levels as riots occurred in the major cities.
Northumbria, northern England
Charles Fox had spent years as Consul to America. Unexpectedly popular among the Americans despite representing William IV, the diplomat had been recalled by order of the King. At the time, Fox assumed that he would be granted a higher post in government. Instead, he returned to England to find his father, Henry Fox, dead and the new puppet-master in London to be Joseph Wall. Wall found the younger Fox dangerous and would send him north with the younger son of William IV, to serve as the Prince's "advisor" in his post as Governor of Northumbria. Eventually, Fox's elder brother, a General, would be posted north as well.
This would prove to be Wall's greatest error as the rebellion would cut off Northumbria, Prince George and his "Foxite" advisors. Northumbria was a conservative region of England, located just south of Scotland. The ERA's radical propaganda was not received well here. However, that did not mean the independent region cared much for King William IV.
When the Parliamentary Armies in Yorkshire and the ERA armies in the mid-land would cut off Northumbria from London, the Foxes would begin plotting with Prince George to increase their own power. Word of this leaked south and whatever Fox property existed in southern England was confiscated. Irate, the Foxes and Prince George would pronounce that Northumbria had seceded from England as the new Kingdom of Northumbria.
In truth, George utterly hated his father whom doted upon his elder brother. A more dysfunctional family could not be imagined than the House of Hanover and George was no different. Taking advantage of this was Scotland's oligarchy, whom deemed George the least threatening to their own power. It had long been feared among the Scots that, bereft of French occupation forces, that William IV would invade Scotland to regain his patrimony.
Scottish money, munitions and advisors flocked southward to Northumbria to aid the young King in forming his forces. The northerners held the advantage of being peaceful enough to gather the harvest (no matter how poor) and even collect taxes (something the rest of England's rival factions could not claim).
Outraged, King William IV would contemptuously refer to George as the "King of the North" and predicted Northumbria would collapse within months.
