Robin Hood is a legendary heroic outlaw originally depicted in English folklore and subsequently featured in literature and film. According to legend, he was a highly skilled archer and swordsman. In some versions of the legend he is depicted as being of noble birth, and having fought in the Crusades before returning to England to find his lands have been taken by the Sheriff. In other versions this is not the case and he is instead born into the yeoman class. Traditionally depicted dressed in Lincoln green, he is said to have robbed from the rich and given to the poor.
