The Yunnaiteddo Independence War was a war between some of the revolting noble houses of the Kingdom of Falglor and the popular King and the rest of Falglor. The fight was based in the Xi Region to the east, with the noble stronghold being located across the Prafian River. The revolting nobles were largely of the Teobu ethnicity, though many other nobles joined the rebels throughout the short war.
Cause
The buildup to the war began with the Age of Frost. For many years, the Kingdom of Falglor was one of the powers left after the collapse of The Alammar Empire. It inherited most of the more developed and richer areas of the Empire, along with most of the military equipment and soldiers of the Royal Army. However, during the Ravennan Famine, King James the First began to run into a few problems. The nobility and the House of Lords, the way the nobles interacted with the governing of the Kingdom, was beginning to be a detriment to his actions. The first Falglorian king had put into place the House of Lords and the nobility in order to win the loyalty of several magnates and other politically important persons and unify the Kingdom. However, with the kingdom unified and in a period of peace, the nobles were beginning to run rampant, slowing down the political process to a standstill in order to struggle for power and influence among themselves, abusing the populace in order to produce more capital and more profits, along with a number of other things.
The problem was only exacerbated with the outbreak of the Age of Frost. While James wanted to aid the forming Coalition of Nations, the nobles were strictly against any intervention, using their influence and resources in order to make the King's effort to join the Coalition against the Armies of Dread as difficult as possible. The King, through careful political maneuvering and support from the people, was able to go against the nobles, but not without much struggle on his part. As a result of this, James's view on the House of Lords and nobility in general dived even worse than it was before.
After the Age of Frost, James decided that the nobles needed to go, and embarked on his own little operation against the nobility. His goal was to either disband the House of Lords and all the nobles entirely, or to deprive the nobility of its influence and power, so that the titles were mainly just ornamental. James set about this task by establishing monumental support among the people, and attempting to use the strategy of dividing and conquering with the nobles. To deal with individual nobles, he would force upon them inflated debts and trumped up criminal charges, either bankrupting or executing nobles. This obviously antagonized a lot of the other nobles, but they were mostly powerless to do anything since the local population was so heavily poised against them, including their own guards. The only place where this was an exception was the Xi Region.
The Xi Region is mostly home to the Teobu peoples, though there are several other ethnic minorities present. Located in the west of the Kingdom, it was a more recent acquisition, part of the Kingdom's early ambition to expand further to the west and dominate the south of the continent. However, with the ascension of James the First into the throne, the expansionist drive that fueled Falglor in the early days was mostly gone. However, there was an important aspect of James that came into consideration when governing the Xi Region and the Teobu people: he was really racist toward them. As such, the Xi Region was never given many of the rights that other provinces of the Kingdom of Falgor were given. The Teobu people were often the target of multiple discriminatory acts, both to gather support from other political figures who hated the Teobu and to fulfill Jame's personal beliefs. As a result, the support with the people the King was able to cultivate throughout the rest of the Kingdom was never really able to manifest here, and the people mostly remained on the side of the nobles. Adding to this divide between the Xi Region and the rest of Falglor, while Falglor is famously culturally diverse, the Teobu people are more so, their culture mostly disconnected from the rest of the Kingdom.
With all these factors combined, the nobles felt heavily threatened, and multiple of the most influential and powerful nobles met up in Dongjing in the Xi Region in order to figure out a plan or course of action. After a day of deliberating, it was decided that they would pool all their resources combined and rebel against the Kingdom, either marching to Wrenin and getting James to undo his actions and replace him with a puppet, or guaranteeing their independence from Falglor.
The Civil War
The Xi Region and the nobles inside declared independence from Falglor on the 24th of Frigus, declaring the Xi Interim National Government, surprising the Kingdom's forces. James had anticipated isolated noble rebellions and as such spread out the Royal Army, and was completely blindsided by the rebellion. Rebel forces quickly grew, composed of house guards, mercenaries, and poorly equipped and trained peasant levies caught up in the tide of nationalism and rebellion.The rebel forces quickly rallied in a combined army under General Taiga Yamada and marched across the Prafian River, quickly defeating the unprepared Falglorian garrisons and defences, taking key cities and coastal locations, along with cutting off one of Falglor's most vital river trade routes.
The spread out Royal Army began to try and slow the advance of the rebels as they marched eastward toward Wrenin, and attempted to group up. In the capital, the King and his cabinet panicked, and considered fleeing the city in case the rebels actually took it, seeing as how the forces under General Taiga were advancing quickly. However, with reassurance from the Marshal and other high-ranking military officers, the King was convinced to stay.
Meanwhile, nobles from across the country fled to the west, seeking either to escape their fate and join with the new regime or to attempt to retain their power by devaluing the power and authority of the king while still keeping the rest of the government. These fleeing nobles were happily greeted by the new Xi Interim National Government, and their resources were put towards the war effort.
However, things were beginning to go wrong for the rebels. They had aimed for a decapitating blow toward Wrenin and the heartland of Falglor, and they seemed to be on track toward a quick victory, they had defeated the sparse units and still recovering legions the Kingdom had sent their way, but they were beginning to run into problems of their own. Yamada had pushed his troops hard, pressured by the nobles and urged on by the gloryhound in him to defeat Falglor quickly in a decisive battle in order to immortalize himself into history forever. This led to him pushing the troops under his command especially hard. The rebel's advantage in the early stage of the war was the element of surprise and the nature of the spread out Royal Army. However, with the war stretching on for a month or two, cracks were beginning to show in the Xi Interim National Government.
For starters, the expeditionary force of the campaign that aimed to take Wrenin were beginning to attrition from continued marching and fighting, not allowed a moment to rest as Yamada desperately attempted to reach Wrenin before the Royal Army managed to regroup. It was reported that sometimes the conscripted peasants would drop dead from the exhaustion halfway through the march, and their bodies would be left there because no one wanted to waste the time needed to pick them up or give them a burial, or waste valuable energy doing so. The nobles of the Xi Interim National Government were also beginning to infight over the goals of the rebellion, debating whether or not to take over the government or to just severely debase the power of the king. Meanwhile, the Royal Army was also beginning to coalesce, throwing units and legions at the advancing rebel army in order to try and slow them down, and would soon be ready with their full might in just a few weeks.
The turning point in the war came with the Battle of Ziech. Ziech was a valuable town in sight of Wrenin and a trading and supply hub. If the rebels managed to take Ziech, it would give them a foothold into the heart of Falglor. Royal Army garrisons were the first to engage the oncoming rebel army, and as time passed and a siege was constructed, the entirety of the western Royal Army began their own surprise assault on the rebel forces, delivering heavy casualties, inflicting a devastating defeat, driving the rebels back into the Xi Region.
After the humiliating defeat at Ziech, Taiga was replaced as head of the rebel forces, but at that point, the course of the war had already been set in motion, and the Interim Government was not in a good position. The rebels were pushed back across the Prafian River, demoralized and out of any fighting spirit. However, the Royal Army was unable to cross the Prafian River themselves despite multiple attempts to do so, or to make any landings on the coast. There was little major engagements during the rest of the war, only the Cloven Estuary Campaign by the Royal Army which ultimately ended in failure.
Resolution
The war started coming to an end when The Order formally recognized the Xi Interim National Government as it's own state, in an attempt to weaken Falglorian power and hegemony over the south, and to undermine their biggest rival. This started a tidal wave from which James and the Kingdom were unable to stop, with the Kingdom of Ravenna recognizing the rebels soon after, followed by Republic of Valdar, and several other southern nations.
Soon after these tide of declarations, James had no choice but to sign a treaty with the Interim Government, creating a white peace over the region, but instilling a generational revanchist sentiment within Falglor over the Xi Region and their perceived western brother oppressed by the nobles. Immediately following this white peace, the nobles splintered, and created The Yunnaiteddo Federation.
