Well, you got an influx to this:

https://en.wikipedia.org/wiki/Varangian_Guard

"Composed primarily of Scandinavians for the first 100 years, the guard began to see increasing numbers of Anglo-Saxons after the successful invasion of England by the Normans.

[..]

the Guard was commonly called the Englinbarrangoi (Anglo-Varangians) [after a point]"

(That is all I really read about that subject.)

Though I seriously don't think that not having English Varangians would've changed the course of Byzantine History-Manizkert, the Crusades, and lots of infighting and civil wars would've probably still happened. Manzikert was only 5 years in the future.

Well, thinking about this a bit more... you could argue that my position is really simplified.

Christianity wasn't that nice either. Exterminating all competing religions (Asatru, Catharism, South American religions etc) and probably even worse pogroms than the Muslim world, etc.

I was answering a question about where the Anglo Saxon nobility went after 1066. I didn't touch the main subject of this discussion (how history would have been different).

Edit: But please expand on the subject, as if I had meant that. It would be interesting. :-)
