During the Industrial Revolution, many workers moved from England's countryside to new and expanding urban industrial areas to work in factories, for instance at Birmingham and Manchester, dubbed "Workshop of the World" and "Warehouse City" respectively. England maintained relative stability throughout the French Revolution; William Pitt the Younger was British Prime Minister for the reign of George III. During the Napoleonic Wars, Napoleon planned to invade from the south-east. However this failed to manifest and the Napoleonic forces were defeated by the British at sea by Lord Nelson and on land by the Duke of Wellington. The Napoleonic Wars fostered a concept of Britishness and a united national British people, shared with the Scots and Welsh.
