The Belgian Civil War is a conflict between the Modern States of Flanders and Wallonia.
Line in The Sand
In 1962, the Belgian government had finally drawn the language line, recognizing the Flemish people. But the Great Nuclear War brought tensions even closer to the brink. Wallonia was hit hard by the fallout from France and Brussels's destruction had destabilized the nation.
The Volksunie, a major Flemish Nationalist party, refused to allow Flanders to surrender aide to the Walloons. With pressure from the south came antagonism between the two peoples, and eventually Flemings took up arms and pushed the francophone militias out of Flanders. This is the beginning of the Civil War.
Most of the fighting occurred between unorganized mobs and loosely chartered militias, with either side trying to acquire farmland and defensible hills. Neither was equipped to handle the unregulated conflict, which was more akin to gang violence than actual war.
On the day of the Great Nuclear War, a NATO general was on his way to Brussels to discuss the Crisis in the Caribbean, but he would never make it there. Brussels was bombed before he could be informed of the war that broke out between the formerly sleepy giants of the world. He and his personal guards were stranded outside the irradiated ruins, desperate to survive. They stumbled upon a surviving garrison of NATO soldiers, where he pulled his rank. Noname took control of the well armed group of regulars, declaring "A New World Order" to be in place. Over the course of two years, he carved his own personal fief out the farms and town around Brussels. Eventually he caught wind of the Civil War when one of his vassal farms was captured by Wallonia.
Upon discovery of the quagmire, the government of Saar sent a small militia by river boat in order to help the Provisional Government of Belgium end the fighting. This backfired horribly, as the troops became convinced of the Flemish cause, staging a devastating bombing in Namur, and causing the war to drag on for another three years.
In 1970, the fighting had dragged on for too long, and people were looking for a way out. General Noname declared his land a place for a meeting between the three budding nations. It was here that official borders were hammered, laws were put into place and peace was brokered. General Noname was of course invested in his own land, and declared his fief a "Buffer Zone", naming it after the historical province of Brabant. Flems and Walloons agreed reluctantly. National Armies were required by the new treaty, as well as a militarization of the border. Saarish representatives were present at this meeting, prepared to pay reparations for damage caused in the Namur Incident.
