There is something very interesting happening in my current game (Byz, Early, Expert): the year is 1229, and the rebels on the Eastern Plains are the most developed nation on the map (besides me). Basically, I turtled after taking out Turks and Egypt, while Neither Poland nor Novgorod were able to make a meaningful land grab (Rebels still control the Prussia-Volhynia-Moldavia line, AND they have knocked PoN out of Novgorod and cornered them into Finland.
Now, the funny thing is that almost every rebel province has a citadel in it, as well as a whole bunch of men (in the hundreds). They have yet to put a ship in the sea though.
All the while most of Europe has been ravaged by non-stop warfare as powers rise, fall, only to re-emerge and repeat the cycle.
I'm sitting tight in Constantinople ready to take on the Horde, and needless to say, the situation is rather amusing.
