Economic decline led to a period of political instability known as the Patriottentijd (1780–87). This unrest was temporarily suppressed by a Prussian invasion in support of the stadtholder. The French Revolution and subsequent War of the First Coalition caused these tensions to reignite. Following military defeat by France, the stadtholder was expelled in the Batavian Revolution of 1795. This ended the Dutch Republic; it was succeeded by the Batavian Republic.
