The Kingdom of Kent was founded by two legendary brother who’s descendants founded the Oiscingas Dynsasty. Though the regnal dates for the earlier kings are known only from Bede, who piously expunged apostates, and seems also to have deliberately suppressed details of short or joint reigns in order to produce an orderly sequence (he had no place for Æðelwald or Eormenred). Generally more than one king ruled in Kent. Some kings are known mainly from charters, of which several are forgeries, while others have been subjected to tampering in order to reconcile them with the erroneous king lists of chroniclers, baffled by blanks, and confused by concurrent reigns and kings with similar or identical names. From 725 AD, the Kingdom of Kent was subject to the Kingdom of Mercia but were directly ruled by king Offa from 785 to 796 AD. Eventually the Kingdom became a principality of the Kingdom of Wessex. From here, they where later amalgamated into the other Anglo-Saxon Kingdoms, and henceforth became known as the Kingdom of England, ruled by a Wessex monarch.
