There would be a mix of fairly recent Magyar (ethnic Hungarian) occupiers, controlling the scattered Slavic and various other groups already in the Carpathian Basin, plus a few small and even more recent Italian enclaves (originally hired to work on the Cathedrals and other prominent buildings, and never left), etc.
I'd suspect that MANY of the coastal trade cities throughout Europe, especially around the Mediterranian, would have extremely diverse ethnic populations, and Constantinople would certainly rank highly among them.
