Byrhtnoth, Ealdorman of Essex, died at the Battle of Maldon. His name is composed of the Old English beorht (bright) and noþ (courage). He is the subject of The Battle of Maldon, an Old English poem; J.R.R. Tolkien's short play in verse, The Homecoming of Beorhtnoth, Beorhthelm's Son; and a modern statue at Maldon.

The Battle of Maldon took place on 11 August 991 AD near Maldon beside the River Blackwater in Essex, England, during the reign of Æthelred the Unready. Earl Byrhtnoth and his thegns led the English against a Viking invasion. The battle ended in an Anglo-Saxon defeat. After the battle Archbishop Sigeric of Canterbury and the aldermen of the south-western provinces advised King Æthelred to buy off the Vikings rather than continue the armed struggle. The result was a payment of Danegeld of 10,000 Roman pounds (3,300 kg) of silver.
