*The ERE controls the entire coast of the Black Sea, and has blobbed with Georgia and conquered its way down adjacent to Jerusalem.
*The HRE is a massive pot of civil war because after however many decades of ruling it, the Von Shauenbergers (Can't ever recall their proper name... They took over in 1115 or so) decided they wanted to convert to some heretic religion or another. On a side note, the HRE is also all of Norway, Sweden, and Finland. They were quite successful until the whole heresy thing. It would be nice to get ahold of that imperial crown, but even with the wars, I'm not sure I want to risk it just yet.
*The duchy of Turov conquered all of the other Russian states, formed Rus, and conquered its way through the Cuman people, only to finish uniting Khazaria just in time for the Golden Horde to show up and conquer them, which turned the entire area into a massive warzone. The Golden Horde is no longer involved, mind - Rus more or less collapsed after it won its freedom. The current liege appears to be insane, so that's probably the problem.
*The Seljuk Turks managed to resist the impulse to mess with the ERE after the first war and have since gotten their butts kicked by the Ilkhanate, with almost identical results as with Rus, at least until they won in a once and for all manner and started conquering the area the Ilkhanate had managed to take... And then the Ilkhanate's leader became a Shiite, so what's left of it is more or less at peace, with the exception of assaulting assorted minor groups.
*The pseudo-empire of England, Brythain, France, Ireland, Aragon, Castille, and Scotland (in that order) has exploded rather dramatically, as the title suggests. This is incidentally the dynasty I was playing as, and it mostly got sparked by William I's great grandson inheriting what amounted to all of southern France. Hilarity ensued, and so did Cathars, which led to a decent chunk of France (and Andalusia) becoming English. Scotland is the most recent bit, as a result of a recent wedding that ended when the Queen of Scotland stabbed the king of Super!England, so my current King is just waiting for her to die so Scotland is part of the super kingdom proper.
*The pseudo-empire of Castille, Leon, Galicia, Navarra, and Aragon united about half of the Iberian peninsula before I moved in, but that was mostly through Jimena inheritance shenanigans. Really, I was doing them a favor by taking that land away - so many civil wars it wasn't even funny... They are still around, as the Kingdom of Leon, Galicia, and Navarra, but their actual holdings are just enough of Northwestern Iberia to hold onto their de jure titles. I should note that the only reason I managed to beat them was because of the wars. Very lucky.
*Al-Andalus is currently a one province minor sharing space with Mauretania, but until I started persecuting them, they were doing well enough, considering they'd conquered enough of Iberia to crown themselves and had also started moving in on the southern bits of Super Leon.
*Denmark performed a hostile takeover of the Lithuania area, and is now slowly consuming Poland.
*Nubia got promptly shot. Then they moved to England, married into assorted courts, and now all of northern England is ruled by vaguely Arab looking people. It's quite strange.
*Egypt/The Shiite Caliph is bigger than when they started, but have started losing ground to the Great Purple Blob that is ERE-Georgia.
*The Sultan of Africa united his general area, took over Sardinia and Sicily in a permanent manner, and actually managed to briefly own Rome. Scary stuff.
*The Knights Templar are living happily in Oxford. I can't quite remember when I told them they could, but I'm pretty sure I gave them permission, so oh well. Their armies are currently hired out by rebellious Germans, like the rest of the holy orders.
*Genoa owns Venice and a chunk of Italy that isn't already ruled by the HRE.
*I'd imagine any minor groups left are quietly hoping none of the above happen to notice them.
*The Irish dukesduchesses and French Dukes have recently decided they don't like me, so it's possible I'm going to be the next blob on the receiving end of Catholic Empire Collapse Syndrome after the HRE. Gonna have to be careful about not converting to any Heresies or anything like that...
Anyway, things are escalating rather quickly, since a rather significant amount of the above happened in the last... 70 years or so. Quite fascinating. I fully intend to acquire the Holy Roman crown, if only so I can make dealing with dukes Someone Else's Problem except for the purpose of rebellions... Dealing with this many vassals at once is kind of difficult, shockingly.
