Manifesto of the Province of Flanders
The Manifesto of the Province of Flanders (1790 Dutch: Manifest van de Provintie van Vlaenderen; modern Dutch: Manifest van de Provincie Vlaanderen) was the declaration of independence of the County of Flanders on 4 January 1790, during the Brabantine Revolution. On this day, the States of Flanders "solemnly declare[d] in the name of the People, the province of Flanders to be an independent State, and definitively withdrawn from its loyalty and obedience to emperor Joseph II, count of Flanders, and from the House of Austria." The States also declared "all officials, lieges and other servants, whoever they may be, free and absolved from all concluded and indebted contracts, and discharged from every oath done to the fallen count of Flanders." Resistance against the reign of Joseph II in the Austrian Netherlands, which worsened in 1786–87 when a number of States refused to pay their taxes (beden) and the landvoogden reversed all reform decrees on their own authority, escalated to open rebellion in the course of 1789, heavily influenced by the simultaneous French Revolution and Liège Revolution which had commenced a few months earlier.
