The Battle of Assandun ended in victory for the Danes, led by Cnut the Great, who triumphed over the English army led by King Edmund Ironside. The battle was the conclusion to the Danish reconquest of England. Cnut ruled England for nearly two decades. The protection he lent against Viking raiders—many of them under his command—restored the prosperity that had been increasingly impaired since the resumption of Viking attacks in the 980s. In turn the English helped him to establish control over the majority of Scandinavia, too.
