The Belgian Revolution from the United Kingdom of the Netherlands erupted on the night of 25 August 1830, following a performance of Daniel Auber's sentimental and patriotic opera La Muette de Portici, a tale suited to fire National Romanticism, for it was set against Masaniello's uprising against the Spanish masters of Naples in the 17th century.
The play caused a riot and the crowd poured into the streets after the performance, shouting patriotic slogans, and swiftly took possession of government buildings.
The affable and moderate Crown Prince William, who represented the monarchy in Brussels, was convinced by the Estates-General on 1 September that the administrative separation of north and south was the only viable solution to the crisis.
King William I attempted to restore the establishment order by force, but the royal army under Prince Frederik was unable to retake Brussels in bloody street fighting on 23 to 26 September.
These take place throughout the French Community, in cities such as Mons, Namur, Huy, Liège, Charleroi and Brussels.
