Order of precedence in Belgium
The Belgian order of precedence (French: Liste de préséance en Belgique, Dutch: Lijst van préséance in België) is the formal ranking used at the Royal court during acts of state. Because the EU, NATO and SHAPE all have their headquarters in Belgium, this list is used every year during formal receptions at court.
