Edgar the Peaceful

Edgar became king of all England in 959 when his older brother Eadwig died, inheriting a realm that had endured Viking invasions for over a century. His reign fell during a rare lull in attacks between the mid-950s and early 980s, and he used the breathing room to back the English Benedictine Reform, a religious movement that reshaped monasteries into acquisitive powerhouses grabbing estates from lay landowners. In the early 970s he overhauled the coinage system, replacing a patchwork of local mints with a standardised currency. He died in 975 at roughly thirty-one, and the succession immediately fractured: his elder son Edward the Martyr took the throne with the Archbishop of Canterbury's support, only to be murdered three years later, making way for his younger half-brother Æthelred the Unready. The chaos that followed made Edgar's sixteen years look even better in hindsight - historians now call it the peak of Anglo-Saxon culture, though some argue the disorder was simply the bill coming due for his heavy hand.
