Icel of Mercia

The Iclingas (also Iclings or House of Icel) were a dynasty of Kings of Mercia during the 7th and 8th centuries, named for Icel (also Icil), great-grandson of Offa of Angel, a legendary or semi-legendary migration age figure who was in turn made to descend from Woden by the Anglo-Saxon royal genealogies.

The Iclingas reached the height of their power under Offa of Mercia (r. 757–796), who achieved hegemony over the other Anglo-Saxon states, and proclaimed himself "King of the English", but the dynasty lost control of Mercia soon after his death. Penda, who became king of Mercia in about 626 and is the first king named in the regnal lists of the Anglian collection, and at the same time the last pagan king of Mercia, gave rise to a dynasty that supplied at least eleven kings to the throne of Mercia. Four additional monarchs were given an Icling pedigree in later genealogical sources but are now believed to have descended from the family by way of Penda's sister.

Icel himself is of debatable historicity; according to Nicholas Brooks, if historical he would have lived sometime between 450 and 525 and was probably considered the founder of the dynasty because he was the first of his line in Britain. Despite the Icelingas' claims of ties with the rulers and mythic heroes of continental Anglia and with the war-god Woden, Brooks suggests that the Icelingas were, before Penda's rise in prominence, no more and no less royal than any of the other ruling houses of the small Midlands peoples as recorded in the Tribal Hidage and assessed as having between 300 and 600 hides of land. Icel's ancestry in genealogical tradition is as follows: Icel son of Eomer son of Angeltheow son of Offa son of Wermund son of Wihtlæg son, grandson or great-grandson of Woden. In this tradition, Icel is the leader of the Angles who migrated to Britain. Icel is then separated from the establishment of Mercia by three generations: Icel's son was Cnebba, whose son was Cynewald, whose son was Creoda, first king of Mercia.
