I cut these:
Wulfhere of Mercia · Æthelred of Mercia · Ethelbald of Mercia · Offa of Mercia · Cœnwulf of Mercia
since they were never called bretwaldas. I think it would be good if we could come up with some better way to represent this information -- take a look at Egbert of Wessex; he has six templates and a vast succession box at the end of his article. Is there a more concise way to do this? Mike Christie (talk) 13:49, 6 December 2008 (UTC)
(edit conflict) Struck the above as I had misread page history. I think it's not the best approach to have a "bretwaldas" template that includes kings who were not bretwaldas. I'd suggest that we either make a separate template for the later kings or don't call this a "bretwalda" template. Mike Christie (talk) 19:58, 7 December 2008 (UTC)
To Tharkuncoll: as I recall, the ASC says Egbert was the eighth to be called bretwalda, implying the other seven were titled that too. Mike Christie (talk) 19:58, 7 December 2008 (UTC)
