Barons are noble titles that originated in medieval Europe, often granted by a king or queen. They typically owned large estates and had significant power over the land and the people living on it. Barons played a crucial role in the feudal system, where they provided military service to the crown in exchange for land and protection. In addition to their land and power, barons were responsible for maintaining order and justice within their territories. They often held courts to settle disputes and enforce laws. Famous barons, like the Barons of Runnymede, were instrumental in historical events, such as the signing of the Magna Carta in 1215, which limited royal authority.
