In the late 8th Century, Northumbria was plagued by weak leadership and collapsed into a state of anarchy caused in part by rivalry between the royal houses of Deira and Bernicia. From 737AD to 806AD, Northumbria had ten kings: three were murdered, five were expelled and two retired to become monks. This instability may well have encouraged the first Viking raiders to attack the Northumbrian coast from 793AD.
