There is a very straight forward geologiske reason why Europe has been so fractioned. The Mongol Horde never had a chance to invade all of it.
But they were also stopped. Ruthless and intelligent means that while everything else might have been slightly tits up, our ability to deal damage has been top notch for milennia. Them meeting armored ranged cavalry against their unarmored ranged cavalry showcased a good place to stop. And then a little lying and cheating later and the Mongols actually allied themselves with the Byzantines. Glorious.
And then the Mongol empire just fell apartheid.
So a bit of luck. And a bit of bastard.
