(from Latin forum, "marketplace"), in medieval Spain, a municipal franchise conferred on a community by the crown or by a noble or bishop. It granted legal incorporation, confirmed local customs or privileges, and might include rights to taxation or self-government. The word is also applied to a code-the Liber Judiciorum of the Visigoths-known in the Middle Ages as the Fuero Juzgo. Because of the great number and variety of the medieval fueros municipales and the tenacity with which the municipalities clung to privileges granted under them, the fueros played an important part in the political, administrative, and judicial history of Spain.
