Edward, byname EDWARD THE ELDER (d. 17 July 924, Farndon on Dee, England), Anglo Saxon king in England, the son of Alfred the Great. As ruler of the West Saxons, or Wessex, from 899 to 924, Edward extended his authority over almost all of England by conquering areas that previously had been held by Danish invaders.
Edward ascended the throne upon his father's death in October 899, and in battle in 902 his forces killed a rival claimant, Aethelwald, who had allied with the Danes. After defeating the Northumbrian Danes at Tettenhall, he set out in August 912 to subdue the Danes of the eastern Midlands and East Anglia. From 910 to 916 he constructed a series of fortified enclosures around his Kingdom of Wessex.
At the same time, his sister, the Mercian ruler Aethelflaed, constructed a complementary series of fortresses in the northwest Midlands. In 917 Edward and Aethelflaed launched a massive offensive, quickly overwhelming the entire Danish army of East Anglia. Upon Aethelflaed's death in June 918, Edward assumed control of Mercia, and by the end of the year the last Danish armies in the Midlands had submitted. By that time Edward's kingdom included all the lands south of the Humber estuary; in 920 he pacified Northumbria. Complete political unification of England was achieved during the reign of his son and successor, Athelstan (reigned 924-939). [Encyclopaedia Britannica]

Well-trained by Alfred, his son Edward 'the Elder' (reigned 899-924) was a bold soldier who defeated the Danes in Northumbria at Tettenhall in 910 and was acknowledged by the Viking kingdom of York. The kings of Strathclyde and the Scots submitted to Edward in 921. By military success and patient planning, Edward spread English influence and control. Much of this was due to his alliance with his formidable sister Aethelflaed, who was married to the ruler of Mercia and seems to have governed that kingdom after her husband's death.
Edward was able to establish an administration for the kingdom of England, whilst obtaining the allegiance of Danes, Scots and Britons. Edward died in 924, and he was buried in the New Minster which he had had completed at Winchester. Edward was twice married, but it is possible that his eldest son Athelstan was the son of a mistress.
