Belgium is a country in Western Europe, bordered by France, Germany, Luxembourg, and the Netherlands. It possesses an established wizarding community, as evidenced by its ability to field a national Quidditch team for international competition. This implies the existence of a hidden magical society with its own governance, likely a department or office affiliated with the Ministry of Magic structure seen in other countries. However, specific details about the history of magic in Belgium, its magical institutions, or the existence of a dedicated Belgian wizarding school are not mentioned in the primary canon. The relationship between its wizarding and Muggle populations remains undocumented.
Belgium does not play a role and is not mentioned in the original seven Harry Potter novels. The country's sole canonical reference occurs in supplementary materials related to the 2014 Quidditch World Cup. The Belgian National Quidditch Team qualified for the 2014 tournament and advanced to the quarterfinals. In a match described as a “bloodbath,” they were defeated by Wales. The Belgian team's Beaters were noted for their particularly aggressive and physical style of play during the game (Pottermore).
No specific magical locations within Belgium, such as wizarding villages, districts, or landmarks, have been identified in any canonical source.
All known information about wizarding Belgium comes from a series of articles written by J.K. Rowling under the guise of characters like Ginny Potter and Rita Skeeter. These articles were published on the Pottermore website to provide backstory and live-style reporting on the 2014 Quidditch World Cup.
