Medieval nobility refers to the social class of landowners and aristocrats during the Middle Ages in Europe. They held significant power and influence, often ruling over large estates and managing the lives of the peasants who worked their lands. Nobles were typically granted titles such as duke, count, or baron, and their status was often hereditary, passed down through generations. Nobles played a crucial role in the feudal system, which was the dominant social structure of the time. They provided military service to the king in exchange for land and protection. In return, they were expected to maintain order and justice within their territories, ensuring the loyalty of their vassals and the well-being of their subjects.
