The Liberation of Hanover took place in November 1813 as part of the War of the Sixth Coalition during the larger Napoleonic Wars. The Electorate of Hanover had been invaded and occupied in 1803 and since then had been divided between the First French Empire and the Kingdom of Westphalia ruled by Napoleon's younger brother Jerome. The historic House of Guelph headed by George III, but by 1813 under the control of the Prince Regent, were restored to their historic territories.
