Jeans were originally pants worn at work. They were traditionally made from denim but also from a variety of material including corduroy. Jeans are believed to have developed from 16th century Indian dungarees. Modern jeans were invented for Californian miners in the 1850s by a fellow called Levi Strauss who lived in San Francisco. Today minors and adults across the world wear jeans. They are an enduring symbol of American freedom.
