Realm of Belgium

As a federation, Belgium has become incredibly difficult to govern. The 2010 and 2019 governmental crisis just prove this, and multiple groups including leading party N-VA have called for a shift towards a confederal system instead, which could solve many problems. Wallonia opposes this for ... reasons.

But what if it could work out? Click here to find out.

Governance
In this case, Belgium would be a semi-loose union of sovereign states that govern their internal affairs independently but remain united for diplomacy, defence etc.

It's anyone's guess how these states would be ordered, but here's a fun idea.


 * The Kingdom of Flanders, which would inherit the monarchy, comprises the Dutch-speaking north of Belgium whose capital is Antwerp. Dutch is the only official language, but Limburgish is recognized and supported in Limbourg. Additionally, Yiddish is recognized in the City of Antwerp.


 * The Walloon Republic would comprise all of Wallonia, excluding Comines-Warneton and the very east of Liège, in the form of a semi-presidential republic. French is the only official lannguage, but Walloon and several offshoots of French (eg. Picard, Champenois) are recognized.


 * The Federation of the East Cantons is a directorial republic including the German-speaking community of Belgium and all bordering areas where German or a variant thereof is widely spoken: Malmedy, Weismes, Baelen, Blieberg, Welkenraedt, Aubel and Limburg an der Weser. German, Luxembourgish, French and Low Dietsch are all official; Walloon is recognized.


 * The Free City of Brussels is a city-state where French and Dutch are both official. The council of the city would rule over it, hence making another directorial republic.

Because their "owner" is still disputed to this day and the subject of controversy and vandalism, both the Flemish and Walloon exclaves of respectively Voeren (French: Fourons) and Comines-Warneton (Dutch: Komen-Waasten) are now condominiums where both states exercise equal sovereignity. Bam, problem solved.
