The Kingdom of Elmet between Mercia and Deira

Elmet (Old English: Elfed) was an independent Brittonic kingdom. It occupied the area of what was later the West Riding of Yorkshire. Elmet appears in records during the Early Middle Ages between the 5th century and early 7th century. Its neighbor to the east was the Anglian kingdom of Deira. The Anglian kingdom of Mercia was to the south. To the west it bordered on the Irish Sea. Elmet was the last surviving British kingdom in the early Anglo-Saxon period.
