Jack Cade's Rebellion was a popular revolt in 1450 against the government of England, which took place in the south-east of the country between the months of April and July. It stemmed from local grievances regarding the corruption, maladministration and abuse of power of the king's closest advisors and local officials, as well as recent military losses in France during the Hundred Years' War. Leading an army of men from south-eastern England, the rebellion's leader Jack Cade marched on London in order to force the government to reform the administration and remove from power the "traitors" deemed responsible for bad governance. Apart from the Cornish rebellion of 1497, it was the largest popular uprising to take place in England during the 15th century.

The City of London, widely referred to simply as the City, is a city, ceremonial county and local government district that contains the ancient centre, and constitutes, along with Canary Wharf, the primary central business district (CBD) of London and one of the leading financial centres of the world. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages, but the modern area referred to as London has since grown far beyond the City of London boundary. The City is now only a small part of the metropolis of Greater London, though it remains a notable part of central London. The City of London is not one of the London boroughs, a status reserved for the other 32 districts. It is also a separate ceremonial county, being an enclave surrounded by Greater London, and is the smallest ceremonial county in England.
