The group emerged from the secret society
Pro aris et focis in the 1780s, and by 1789 had become a distinct faction. The Vonckists called for Belgian independence from the
Habsburg monarchy under a popular government along the model seen during the
French Revolution. After the
proclamation of the
United Belgian States in January 1790, the Vonckists were denounced as anticlerical by the Statists and many were hunted down by mobs in what was known as the "Summer Terror". Jan Frans Vonck and many other Vonckist leaders were forced into exile in France. Due to the initial persecutions by the Statists and the later suppression of the revolution by the Habsburgs, many Vonckists would flee to France. There, together with leaders of the failed
Liège Revolution, they formed the
Committee of United Belgians and Liégeois, aimed at restoring Belgian independence, as well as merging with the
Prince-Bishopric of Liège into a single state. The committee also closely collaborated with the French government. Following the French annexation of Belgium, many former Vonckists would join
Jacobin clubs, mainly
Girondin ones, though some more radical Vonckists joined the
Montagnards. == Ideology ==
