The Quota System (also known as The Quod), introduced by Prime Minister William Pitt the Younger in 1795, required each British county to provide a quota of men for the Royal Navy, based on its population and the number of its seaports: London, for example, had to provide 5,704 quotamen while Yorkshire had to provide 1,081. Britain ended the quota system, along with impressment, in 1815 at the close of the Napoleonic Wars, when much of the fleet was decommissioned and the supply of unemployed seamen was more than adequate to man the remaining ships.
