Eanfrith of Bernicia

Eanfrith (590–634 ) was briefly King of Bernicia from 633 to 634.

Eanfrith married a Pictish princess and had a son, Talorcan, who later became a king of the Picts (653–657). Edwin was killed by the army of Cadwallon ap Cadfan of Gwynedd and Penda of Mercia at the Battle of Hatfield Chase in October 633, If there was a friendly relationship between Eanfrith and Cadwallon at first, however, it must not have lasted, since Bede reports that Eanfrith went to Cadwallon "with only twelve chosen soldiers" in an attempt to negotiate peace, but Cadwallon had him killed.

The year in which he and Osric ruled was subsequently deemed so abhorrent because of their paganism that it was decided to add that year to the length of the reign of the Christian Oswald of Bernicia (Eanfrith's brother), who defeated Cadwallon and came to rule both Bernicia and Deira, so as to ignore the brief reigns of Eanfrith and Osric.
