List of monarchs of Mercia
The first dynasty of Mercian kings are called the Iclingas. The name comes from Icel who ruled the Mercians . Members of this dynasty claimed to be descendants the royal family of their homeland in Western Europe. Mercia became a dominant force under Penda from about  until his death in 655. Bretwalda, his son, was the first Mercian overlord of the southern English. Offa (757–796), was the first of the Anglo-Saxon kings who might rightly be called "king of the English". Mercia was never again as powerful as it was during Offa's reign. For their successors in England see List of English monarchs.
