William V, Prince of Orange (Willem Batavus) was the last Stadtholder of the Dutch Republic. He went into exile to London in 1795. He was the reigning Prince of Nassau-Orange until his death in 1806. In that capacity he was succeeded by his son William.
William Batavus was born in The Hague on 8 March 1748, the only son of William IV, who had the year before been restored as stadtholder of the United Provinces. He was only three years old when his father died in 1751, and a long regency began. William V assumed the position of stadtholder and Captain-General of the Dutch States Army on his majority in 1766. However, he allowed the Duke of Brunswick to retain a large influence on the government with the secret Acte van Consulentschap. On 4 October 1767 in Berlin, Prince William married Princess Wilhelmina of Prussia, the daughter of Augustus William of Prussia, niece of Frederick the Great and a cousin of George III.
William V joined the First Coalition against Republican France in 1793 with the coming of the French Revolution. His troops fought bravely in the Flanders Campaign, but in 1794 the military situation deteriorated and the Dutch Republic was threatened by invading armies. The year 1795 was a disastrous one for the ancien régime of the Netherlands. Supported by the French Army, the revolutionaries returned from Paris to fight in the Netherlands, and in 1795 William V went into exile in England. A few days later the Batavian Revolution occurred, and the Dutch Republic was replaced with the Batavian Republic.
The last of the Dutch stadtholders, William V died in exile at his daughter's palace in Brunswick, now in Germany. His body was moved to the Dutch Royal Family crypt in the Nieuwe Kerk in Delft on 29 April 1958. In 1813, his son, King William I returned to the Netherlands and became the first Dutch monarch from the House of Orange.
