The HRE decided to make an antipope and then the first crusade failed because the Catholic forces were blessed with a leadership made of absolute retards, so Catholicism's moral authority tanked. This led to this heretical fun.
From left to right, you have:
Norway (they lost their war with England, which is under the Norman yoke. The Ynglings then got kicked off the throne and Norway fell into a state of civil war. I later discovered that one of my vassals had the same culture and religion as me after forming Hispania and also had a weak claim, so of course I decided to
invade freedomise it)
The County of Gudbrandsdalen (peasant uprising)
The High Chiefdom of Jamtland (Germanic revolt, which also controlled the duchy of Nordland as well. They got kicked out of Nordland by a Catholic revolt after I took this picture)
The Duchy of Ostrogothia (Cathar revolt)
The Chiefdom of Närke (Germanic revolt, no idea why the peasant leader didn't get a duchy)
The Swedish Revolt (Germanic, trying to put one of Erik the Heathen's daughters on the throne)
Sweden (barely surviving)
Then, the past decided to predict the future:
Odin God Allah only knows what happened here.
