Pieter Vreede (October 8, 1750– September 21, 1837), was a Dutch politician of the Batavian Republic in the 18th century. Vreede was born in Leiden and died in Heusden. He was a prominent critic of stadholderian misrule and of the urban patriciate.
In Leiden, Vreede worked as a cloth and wool manufacturer, as his father had. Pieter Vreede was member of the Maatschappij der Nederlandsche Letterkunde (organization of writers and readers) and published some writings about the bad shape of the Dutch society.
The patriotic revolution broke out in the 1780s in the Netherlands and Pieter Vreede was one of the enthusiastic participants. Pieter and his friend Wijbo Fijnje made a constitution for Leiden, a founder of the local exercitiegenootschap, a drill society and drafted the celebrated Programme which proposed transforming the United Provinces into a unitary democratic Republic. In 1786, he became a member of the revolutionary town council of Leiden. The infamous Vreede joined in a diplomatic expedition in Woerden in 1786. The revolution came to an end, when the Prussian army invaded the Netherlands in 1787. Pieter lost his business in Prussian Emmerich, so his business was reverted to Lier in the Austrian Netherlands.
Revolution broke out in the Austrian Netherlands as well in 1790, when the United States of Belgium were proclaimed. Pieter left Leiden, stopped his business in Lier and settled in Brabant of the States in the city Tilburg, where he continued his business as cloth and wool manufacturer until 1800.
France conquered Brabant in 1794 and Pieter Vreede immediately sided with the French. The French were very popular in the Netherlands. Many regarded the orangist regime as wrong due to the events of 1787. In 1794, he became a member of Batavian committee of Den Bosch. The same year, he became a member of the revolutionary committee of Brabant. The French continued their advance into the Netherlands and Pieter Vreede became a member of the administration of the conquered areas of the Netherlands in January 1795. Revolution broke out in the Netherlands and William V, Prince of Orange had to flee to England. The Batavian Republic was proclaimed.
