Thane is an Old English term used to describe a feudal lord or nobleman in medieval England. Thegns were the highest ranking members of the nobility and held a variety of responsibilities, including military service, judicial duties, and land management. They were also responsible for collecting taxes and providing protection to their people. The term 'thegn' is derived from the Old English word þegn, which means 'SERVANT' or 'ATTENDANT'. Thegns were often appointed by kings and other rulers to serve as their representatives in local areas.
