The Brabant Revolution or Brabantine Revolution (French: Révolution brabançonne; Dutch: Brabantse Omwenteling), sometimes referred to as the Belgian Revolution of 1789–1790 in older writing, was an armed insurrection that occurred in the Austrian Netherlands (modern-day Belgium) between October 1789 and December 1790. The revolution, which occurred at the same time as revolutions in France and Liège, led to the brief overthrow of Habsburg rule and the proclamation of a short-lived polity, the United Belgian States.
The revolution was the product of opposition which emerged to the liberal reforms of Emperor Joseph II in the 1780s. These were perceived as an attack on the Catholic Church and the traditional institutions in the Austrian Netherlands.
