The regnal dates for the earlier kings are known only from Bede, who piously expunged apostates (Unde cunctis placuit regum tempora computantibus, ut ablata de medio regum perfidorum memoria, idem annus sequentis regis), 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. It is commonplace for the later kings to be referred to as subkings, but the actual rank used is always rex, never regulus (except for a late legend concerning Eormenred). The usual style was simply King of Kent (rex Cantiae) or King of the Kentish Men (rex Cantuariorum). Territorial division within Kent is not alluded to, except by Eadberht I (rex Cantuariorum terram dimidii) and Sigered (rex dimidie partis prouincie Cantuariorum).
