The Northumbrian king became in fact supreme over Britain as no king of English blood had been before.

Northward his frontier reached to the Firth of Forth, and here, if we trust tradition, Eadwine founded a city which bore his name, Edinburgh, Eadwine's burgh.

To the west his arms crushed the long resistance of Elmet, the district about Leeds; he was master of Chester, and the fleet he equipped there subdued the isles of Anglesea and Man.

South of the Humber he was owned as overlord by the five English states of Mid-Britain.

The West-Saxons remained awhile independent.
