Ealdorman (/ˈɔːldərmən/ AWL-dər-mən or /(eɪ)ˈældərmən/ (ay-)AL-dər-mən, Old English: [ˈæɑɫdorˌmɑn])[1] was an office in the government of Anglo-Saxon England.
The title could be applied to kings of weaker territories who had submitted to a greater power.
For example, a charter of King Offa of Mercia described Ealdred of Hwicce as "subregulus ... et dux ('underking and ealdorman').
[3] In the 10th century, the kings of Wessex successfully unified England into one kingdom, and ealdormen became the local representatives of the monarch.
[4][5] Starting with Edward the Elder (r. 899–924), it became customary for one ealdorman to administer three or four shires together as an ealdormanry.
