King Æthelred the Unready was the King of England from 968 to 1016. He is often remembered for his struggles against Viking invasions during his reign. His nickname, "Unready," comes from the Old English word "unræd," meaning "ill-advised" or "poorly prepared," reflecting his difficulties in leadership and decision-making. Despite his challenges, Æthelred attempted various strategies to defend his kingdom, including paying tribute to the Vikings. His reign saw significant turmoil, leading to his eventual exile and the rise of Sweyn Forkbeard, a Danish king, who briefly ruled England before Æthelred returned to the throne.
