Edmund I of England

King Edmund I of England, or Edmund the Deed-Doer was born in Wessex in 921 as a son of Edward I the Elder of England, King from 899 till 924, and half-brother of Athelstan of England, king from 924 till 939.

Athelstan died on October 27, 939 and Edmund succeeded him as King. Shortly after his preclamation as king he had to face several military threats. King Olaf I of Dublin conquered Northumbria and invaded the Midlands. When Olaf died in 942 Edmund reconquered the Midlands. In 943 he became the god-father of King Olaf of York[?]. In 944, Edmund was successful in reconquering Northumbria. In the same year his ally Olaf of York lost his throne and left for Dublin in Ireland. Olaf became the king of Dublin as Olaf Cuaran and continued to be allied to his god-father. In 945 Edmund conquered Strathclyde but conceded his rights on the territory to King Malcolm I of Scotland. In exchange they signed a treaty of mutual military support. Edmund thus established a policy of safe borders and peaceful relationships with Scotland. During his reign, the revival of monasteries in England began.

Edmund was murdered in 946 by Leofa, an exiled thief. He had been having a party in Pucklechurch, when he spotted Leofa in the crowed. After the outlaw refused to leave, the king and his advisors fought Leofa. Edmund and Leofa were both killed. He was succeeded as king by his brother Edred, king from 946 until 955.

Edmund's sons later ruled England as:

• Edwin of England, King from 955 till 957, king of only Wessex and Kent from 957 until his death on October 1, 959.
• Edgar of England, king of only Mercia and Northumbria from 957 until his brother's death in 959, then king of England from 959 till 975.
