Aethelfrith and Edwin 598AD-633AD
Northumbria, "North of the Humber" was an Anglo-Saxon kingdom formed by merging Bernicia, north of the Tees, with Deira to the south. Northumbria's first two kings were a Bernician called Aethelfrith and a Deiran called Edwin. Aethelfrith was a pagan, but Edwin became the North's first Christian king after baptism at York in 627AD.

The Catterick area was the scene of fierce resistance against the Romans in earlier centuries.

The Dalriada Scots live in western Caledonia and originate from Hibernia (Ireland) and were assisted by a large force of Ulstermen in the battle. Aethelfrith's victories in battle have forced the kingdoms of Strathclyde in the west, Rheged in Cumbria and Gododdin in the Lothians to recognise Bernician superiority.

Bamburgh has continued to be known by its old Celtic name despite its capture by the Anglo-Saxon chief Ida in 547. Since that time it has been the chief fort and capital of northern Northumbria. The site's new name means Bebba's fort.

The assassin entered the King's court and asked to speak with the king on the pretence of having an important message from the West Saxon King. On seeing the king, Eumer produced a poisoned dagger from beneath his cloak and attempted to stab Edwin. Fortunately one of Edwin's men, Lillam, jumped in the way and was killed. A fight followed in which Edwin was injured but Eumer was eventually put to death. On the same night Edwin's queen, Ethelburga, gave birth.
