Smuggling is the illegal transportation of objects, substances, information or people, such as out of a house or buildings, into a prison, or across an international border, in violation of applicable laws or other regulations. There are various motivations to smuggle. These include the participation in illegal trade, such as in the drug trade, illegal weapons trade, prostitution, human trafficking, kidnapping, exotic wildlife trade, art theft, blood diamonds, heists, chop shops, illegal immigration or illegal emigration, tax evasion, import/export restrictions, providing contraband to prison inmates, or the theft of the items being smuggled. Smuggling is a common theme in literature, from Bizet's opera Carmen to the James Bond spy books (and later films) Diamonds Are Forever and Goldfinger. Etymology The verb smuggle, from Low German smuggeln or Dutch smokkelen (="to transport (goods) illegally"), apparently a frequentative formation of a word meaning "to sneak", most likely entered the English language during the 1600s–1700s. Smuggling has a long and controversial history, probably dating back to the first time at which duties were imposed in any form, or any attempt was made to prohibit a form of traffic. Smuggling is often associated with efforts by authorities to prevent the importation of certain contraband items or non-taxed goods; however, there has also been smuggling based on illegally exporting goods. In England smuggling first became a recognised problem in the 13th century, following the creation of a national customs collection system by Edward I in 1275. Medieval smuggling tended to focus on the export of highly taxed export goods — notably wool and hides. Merchants also, however, sometimes smuggled other goods to circumvent prohibitions or embargoes on particular trades. Grain, for instance, was usually prohibited from export, unless prices were low, because of fears that grain exports would raise the price of food in England and thus cause food shortages and/or civil unrest. Following the loss of Gascony to the French in 1453, imports of wine were also sometimes embargoed during wars to try and deprive the French of the revenues that could be earned from their main export. Most studies of historical smuggling have been based on official sources — such as court records, or the letters of Revenue Officers. A senior academic of the University of Bristol states that they only detail the activities of those dumb enough to get caught. This has led him and others, such as Prof. H. V. Bowen
