William I’s ‘Harrying of the North’ was a military expedition against local rebels and a Danish invasion force in the winter of 1069–70. It has been regarded since the 1870s as a uniquely savage treatment of the English inhabitants of northern England, wantonly destructive of life and the means of sustenance, and tantamount to genocide. Such views derive from the two fullest medieval accounts, by the early twelfth-century historians Symeon of Durham and Orderic Vitalis. However, neither was an eye-witness, both were at work two generations later, and both had their own agenda in describing the destruction of the North and William I’s cruelty. The Harrying should instead be seen as a routine military operation which took place, unusually, in the depths of winter, and so had unusually severe consequences. More strictly contemporary accounts from Evesham and Beverley reveal a regional but probably localized famine and a refugee crisis. Further, the record in Domesday Book (1086) of many Yorkshire villages as ‘waste’ should be read as referring not to physical destruction but to the absence of surplus values accruing to landlords, and not caused by the Harrying alone. The Harrying of the North was no genocide.
