These are the dates for their reign, beginning to end. There are some cases where the end of the reign was not the end of their life, so I give the death date if I know it. I have tried to give some indication (where I can) of how they died (or ended their reign.)
ab. = abdicated, kib. = killed in battle, as. = assassinated, ex. = executed, dep = deposed
Northumbria is located in the north of England, basically the whole of England north of the Trent. Plus a bit of southern Scotland.
