Mercia was the big 'un before the emergence of Wessex as the leader of the resistance against the (continued) invasion by the Danes. Alfred (the only English king known as "the Great") battled the Danes over the Danegeld extortion. Eventually Svein Forkbeard spent 20 years preparing an invasion force (some of the old barracks sites and such have been excavated) then died, leaving the task of the conquest to his son, Knut -- the eventual King Canute of England. That dynasty didn't take root.
Mercia's King Offa built an earthwork along his frontier with Wales, known as Offa's Dyke. Recent research has shown that a much smaller surviving work, Wat's Dyke in Wales, wasn't built in response, but in fact antedates Offa's by centuries.
But anyway, this guy, whatever the name, wasa pagan, so...
Give us back our bones, pagans tell museums

Offa's Dyke
The people who live 'behind' Offa's Dyke have the highest % of 'O' type blood of anywhere in Europe.
