A map depicting The War of Six Kings: the second great civil war within the Carolingian Empire following the deposition of Emperor Charles III "the Fat" in the year 890 AD. East Franicia is black while its client states are a dark grey. Lotharingia is a dark blue while its client states are a lighter shade of blue. Neustria is the turquoise colored state while Aquitaine is a reddish orange colored. Great Moravia is the pale blue colored state. The Sardinian Judicates are lavender colored while Italy proper is a dark green. The Kingdom of Astruias is yellow, while Pamplona is brownish orange.
After doing more research, I've dug up my old outlines and map ideas for the Carolingian Empire and created this map. I'm planning to eventually start a new timeline regarding a surviving Carolingian Empire following the deposition of Charles the Fat. Here unlike otl, Carolingian Empire has essentially fractured into six different petty kingdoms during the Interregnum before its finally re-united.
The main divergence from otl in this timeline is that Pope Adrian III manages to live a bit longer than otl and is able to meet with Emperor Charles III legitimizing his son Bernard. This allows Charles to name his son the King of Lotharingia in 885.
In 887, angered by his uncle's actions which now place him out of the line of succession, Arnulf of Carinthia like in otl uses the discontent among the nobility and clergy with Charles for his perceived incompetence and lack of martial prowess to rebel against him. He marched at the head of a small force taking into custody both Charles and Bernard. He then called a Diet at Tribur where he formally deposed Charles of his throne in East Francia. Bernard however much to his cousin's chagrin escaped, thanks to the aid of Charles' loyal Alemannians. He then quickly made his way to Lotharingia where in Aachen he proclaimed himself the rightful ruler of the Empire. However because of his fairly young age and short time on the throne, his reign in Lotharingia was quite tenuous as there were many nobles who supported Arnulf of Carinthia.
Within the rest of the Empire however, seeing the power vacuum forming, each Kingdom elected a king for itself. Within Neustria (West Francia), the powerful Count Odo, who distinguished himself in the Viking siege of Paris was elected. However he was unable to take over Southern France as Rainulf II of Poitou managed to secure for himself the Crown of Aquitaine. Burgundy fractured into two with the Kingdom of Provence falling under Louis the Child (the son of Boso I) while upper Burgundy was ruled by Rudolph I. Upper Burgundy however swore fealty to King Arnulf while Bernard cut a deal with Louis the Child's court and accepted his fealty promising him the entirety of Burgundy once Arnulf was dealt with.
Within East Francia, a revolt broke out in Alammania where most of it's nobles revolted in favor of Bernard forcing Arnulf into action who also had to deal with the threat of the expansionist power to the East: Great Moravia.
Within Italy Guy of Spoletto siezed the Iron Crown now that throne in Pavia was vacant. With the Papacy and most of the Italian nobles on his side, he also proclaimed himself Emperor.
What do you guys think of the map? It's been honestly been a while since I made maps like this so I'm a bit rusty.
