Not strange per se... but infuriating. A german Karling on the ERE throne.
And instead of becoming a greek orthodox, now all the ERE (including Italy, Bavaria and the original Byzantine empire) is Catholic and German.
And this consolidated the Karling power on Europe. West Francia has been West Francia for centuries, England saw a couple of Karlings on the throne too, Anatolia was later gained on a crusade and is ruled by anglo-saxon Karlings.
The only place without Karlings is Iberia and, somehow, Aquitaine.
