Mercia

Mercia (Old English: Mierce, "border people"; IPA: ) was one of the kingdoms of the Anglo-Saxon heptarchy, centred on the valley of the River Trent and its tributaries in what is now the Midlands of England.

Mercia's neighbours included Northumbria, Powys, the kingdoms of southern Wales, Wessex, Sussex, Essex, and East Anglia. The term survives today in the name of the West Mercia Constabulary, commercial radio station Mercia FM in Coventry, and also in two regiments of the British Army, the new Mercian Regiment, and the Royal Mercian and Lancastrian Yeomanry.
