The Liège Revolution, sometimes known as the Happy Revolution (; ), against the reigning prince-bishop of Liège, started on 18 August 1789 and lasted until the destruction of the Republic of Liège and re-establishment of the Prince-Bishopric of Liège by Austrian forces in 1791. The Liège Revolution was concurrent with the French Revolution and its effects were long-lasting and eventually led to the abolition of the Prince-Bishopric of Liège and its final annexation by French revolutionary forces in 1795.
