Antiquity Belgium Europe

So here is a map of what Europe would look like if Belgium would have kept its former territories from antiquity (and kept the territories it has now). It's based on this map : [link]
The accuracy may not be perfect, I'mnot used to work on/with maps, but it gives a good overview anyway.
I was annoyed by all these alternate history maps where Belgium is swallowed by France, Netherlands or Germany, while our territory, in matter of name, is historically and technically more ancient than France and Netherlands (as Franks arrived in Belgium and "France" only in the 5th century).
So, a lot of our lands were stolen by Germany, France and Netherlands. But I'm not one of those dumb patriots or nationalists who want to "reconquer" "our land" (and this kind of people doesn't really exist in Belgium either, chauvinism and national pride are for barbarians, personally.)
