The Grand Jubilee of 1814 was a public holiday and celebration in the United Kingdom held on 1 August 1814. The event marked the 100th anniversary of the accession of George I, the first king of the House of Hanover, the 16th anniversary of Horatio Nelson's victory at the Battle of the Nile and the recent signing of the Treaty of Paris, bringing an end (briefly) to the Napoleonic Wars.
