The predecessor of Britain's modern His Majesty's Coastguard was established in 1809 as the Waterguard, a department of the HM Customs and Excise authority, which was originally devoted to the prevention of smuggling.
At the time, due to high UK taxation on liquors such as brandy, as well as tobacco and other luxuries, smuggling of such cargos from places such as France, Belgium, and Holland was an attractive proposition for criminals.
The barrels of brandy and other contraband were landed from the ships on England's beaches at night in small boats and later sold for profit, as later depicted in the Doctor Syn series of books by Russell Thorndike.
