The Patriottentijd (Dutch, literally "Patriot Period") is a period of political upheaval in the Dutch Republic between approximately 1780 and 1787.
The period takes its name from the radical political faction known as the Patriots (Patriotten) ed by Joan van der Capellen tot den Pol, gaining power from November 1782.
They are inspired by Enlightenment ideas.
The Patriots oppose the Orangists and the rule of William V, Prince of Orange.
In 1787, the Patriots are defeated by a Prussian army and many are forced into exile.
