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

Despite Cade's attempt to keep his men under control,
once the rebel forces had entered London they began to loot.
The citizens of London turned on the rebels & forced them
out of the city in a bloody battle on London Bridge. To
end the bloodshed the rebels were issued pardons by the
king & told to return home. Cade fled but was later caught
on 12 July 1450 by Alexander Iden, a future High Sheriff
of Kent. As a result of the skirmish w/Iden, the mortally
wounded Cade died before reaching London for trial. The
Jack Cade Rebellion has been perceived as a reflection
of the social, political, & economic issues of the time
period & as a precursor to the Wars of the Roses which
saw the decline of the Lancaster dynasty and the rise
of the House of York.
