MerciaMercia (ˈmɜrʃiə,-ʃə,-siə, Miercna rīċe; Merciorum regnum) was one of the three main Anglic kingdoms founded after Sub-Roman Britain was settled by Anglo-Saxons in an era called the Heptarchy. It was centred on the River Trent and its tributaries, in a region now known as the Midlands of England. A Latinisation of an Old English word derived from the Mercian Old English, Merce, meaning "borderland" (whence the Modern English words mark and march), the kingdom was rendered as Mierce or Myrce in the West Saxon dialect.
Alfred the GreatAlfred the Great (also spelled Ælfred; 849 – 26 October 899) was King of the West Saxons from 871 to 886, and King of the Anglo-Saxons from 886 until his death in 899. He was the youngest son of King Æthelwulf and his first wife Osburh, who both died when Alfred was young. Three of Alfred's brothers, Æthelbald, Æthelberht and Æthelred, reigned in turn before him. Under Alfred's rule, considerable administrative and military reforms were introduced, prompting lasting change in England.
NorthumbriaNorthumbria (nɔrˈθʌmbriə; Norþanhymbra rīċe; Regnum Northanhymbrorum) was an early medieval Anglo-Saxon kingdom in what is now Northern England and south-east Scotland. The name derives from the Old English Norþanhymbre meaning "the people or province north of the Humber", as opposed to the people south of the Humber Estuary. Northumbria started to consolidate into one kingdom in the early seventh century, when the two earlier core territories of Deira and Bernicia entered into a dynastic union.
Anglo-SaxonsThe Anglo-Saxons were a cultural group that inhabited much of what is now England in the Early Middle Ages, and spoke Old English. They traced their origins to settlers who came to Britain from mainland Europe in the 5th century. Although the details are not clear, their cultural identity developed out of the interaction of incoming groups of Germanic peoples, with the pre-existing Romano-British culture. Over time, most of the people of what is now southern, central, northern and eastern England came to identify as Anglo-Saxon and speak Old English.
