Jeans are a type of pants or trousers made from denim or dungaree cloth. Often the term "jeans" refers to a particular style of trousers, called "blue jeans", with copper-riveted pockets which were invented by Jacob W. Davis in 1871 and patented by Davis and Levi Strauss on May 20, 1873. Prior to the patent, the term "blue jeans" had been long in use for various garments (including trousers, overalls, and coats), constructed from blue-colored denim. "Jean" also references a (historic) type of sturdy cloth commonly made with a cotton warp and wool weft (also known as "Virginia cloth"). Jean cloth can be entirely cotton as well, similar to denim. Originally designed for miners, modern jeans were popularized as casual wear by Marlon Brando and James Dean in their 1950s films, particularly The Wild One and Rebel Without a Cause, leading to the fabric becoming a symbol of rebellion among teenagers, especially members of the greaser subculture. From the 1960s onwards, jeans became common among various youth subcultures and subsequently young members of the general population. Nowadays, they are one of the most popular types of specialty trousers in Western culture. Historic brands include Levi's, Lee, and Wrangler. Research on the trade of jean fabric shows that it emerged in the cities of Genoa, Italy, and Nîmes, France. Gênes, the French word for Genoa, may be the origin of the word "jeans". In Nîmes, weavers tried to reproduce jean fabric but instead developed a similar twill fabric that became known as denim, "de Nîmes" , meaning "from Nîmes". Genoa's jean fabric was a fustian textile of "medium quality and of reasonable cost", very similar to cotton corduroy for which Genoa was famous, and was "used for work clothes in general". The Genoese navy equipped its sailors with jeans, as they needed a fabric that could be worn wet or dry. Nîmes's "denim" was coarser, considered higher quality, and was used "for over garments such as smocks or overalls". In 1576, a quantity of "jean fustians" arrived into the port of Barnstaple on a vessel from Bristol.
