|Belgium split in two (or three, depending on who and where you are)|
What is really interesting, however, is that though this separation hasn't always existed (indeed, Belgium used to be a Celtic country before the "Germans" and Romans invaded them), this boundary between the two regions is perhaps much older than one might think, and takes us all the way back to...

Those living north of the road, in what was then considered the poorer regions, were the Salian Franks (from where the Merovingians originated), who came in from the Rhine delta, and became the Flemish's ancestors.
South of this road were the Gallo-Romans whose language is the ancestor of Wallonia's dialects.

Another interesting regional language tidbit is the fact that the southern part of Belgium (Arlon) along with Luxembourg both speak a third dialect which resembles German in many ways. This dialect descends from the Ripuarian Franks whose domain covered the area between the Meuse and Rhine rivers.
