Trousers (pants in North America) are an item of clothing worn from the waist to the ankles, covering both legs separately (rather than with cloth extending across both legs as in robes, skirts, and dresses).
In the UK the word "pants" generally means underwear and not trousers.Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower depending on the style of the garment. To distinguish them from shorts, trousers may be called "long trousers" in certain contexts such as school uniform, where tailored shorts may be called "short trousers", especially in the UK.
In most of the Western world, trousers have been worn since ancient times and throughout the Medieval period, becoming the most common form of lower-body clothing for adult males in the modern world, although shorts are also widely worn, and kilts and other garments may be worn in various regions and cultures. Breeches were worn instead of trousers in early modern Europe by some men in higher classes of society. Since the mid-20th century, trousers have increasingly been worn by women as well. Jeans, made of denim, are a form of trousers for casual wear, now widely worn all over the world by both sexes. Shorts are often preferred in hot weather or for some sports and also often by children and teenagers. Trousers are worn on the hips or waist and may be held up by their own fastenings, a belt or suspenders (braces). Leggings are form-fitting trousers, of a clingy material, often knitted cotton and spandex (elastane).
Villein, or villain, was a term used in the feudal era to denote a peasant (tenant farmer) who was legally tied to a lord of the manor – a villein in gross – or in the case of a villein regardant to a manor. Villeins occupied the social space between a free peasant (or "freeman") and a slave. The majority of medieval European peasants were villeins. An alternative term is serf, from the Latin servus, meaning "slave". A villein could not leave the land without the landowner's consent.
The term derives from Late Latin villanus, meaning a man employed at a Roman villa rustica, or large agricultural estate. The system of tied serfdom originates from a decree issued by the late Roman Emperor Diocletian (ruled 284–305) in an attempt to prevent the flight of peasants from the land and the consequent decline in food production. The decree obliged peasants to register in their locality and never leave it; they could leave their villages only to deliver a message or to accompany their lord to war.
