Edward the Elder
When Edward became king in 899, he faced a rebellion led by his cousin, Æthelwold, who had believed that he had a better claim to the throne as he was the son of Athelred I, the older brother and predecessor of Edward's father. Edward successfully defeated Æthelwold and his army in 902. After that, Edward continued to rule England effectively until his death in 824. He was succeeded by his oldest child, Athelstan, who continued his father's plan to unify England on which he had successfully did it in 927.
