Britain celebrated a Grand Jubilee to mark 100 years since the accession of George I and 16 years since the start of the Battle of the Nile.

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.

George I was King of Great Britain and Ireland from 1 August 1714 and ruler of the Electorate of Hanover within the Holy Roman Empire from 23 January 1698 until his death in 1727. He was the first British monarch of the House of Hanover.

The Battle of the Nile was fought between the Royal Navy and the French Navy at Aboukir Bay in Egypt between 1–3 August 1798. It was the climax of the Mediterranean campaign of 1798, which had started three months earlier after a large French fleet sailed from Toulon to Alexandria carrying an expeditionary force under Napoleon. A British fleet, led by Rear-Admiral Sir Horatio Nelson, decisively defeated a French fleet under Vice-Admiral François-Paul Brueys d'Aigalliers, which had escorted Napoleon's army to Egypt.
