King Ecbert rules the largest part of England; Wessex. He is based on a king that ruled England from 802 CE. In the TV series Ecbert seems to have just as much interest in Christianity as he does in the other pagan religions. He is portrayed by actor Linus Roache.
King Ecbert appears in Season 2 as one of the kings battling against the viking raids. He takes Athelstan under his wing in order to learn more about the vikings he hopes to defeat.
