Yes! King Béla III shows up! I love him
Also, funny to see Dietrich von Saxony. The KGCM Team put together English and German there. It should be Dietrich von Sachsen.
BTW, it should be interesting to see the meeting of Barbarossa and Emperor Manuel. They were rivals and the (real) Emperor even supported and financed the Lombard League against the Kaiser. Maybe Barbarossa can give up on his claims of Southern Italy and an alliance can be forged? Also, remember that Béla is a good friend of Emperor Manuel. Béla was his adopted son and until 1168 the heir-apparent to the Roman throne.
Now, here is the first criticism to your TL: you have made the same error as you did with your other AAR.
Byzantines!
I suggest you to call them Greeks (if the POV is Western European, otherwise Roman will be fine).
