The capital should be Dijon and the UU should be the Bombard
I was doubting whether I should propose Brussels or Dijon for capital. You see, the Burgundian court was centered in Brussels, for practical purposes.
The problem the Burgundians faced was connecting the landmasses of Burgundy (proper) and Brabant, Namur, Flanders, etc... (French: "Les pays de par deça" Dutch: "De landen van herwaarts over").
It was that what would mean the end of them eventually.
