In the Domesday Book of 1086, the town was named "Waras" from the natural weirs in the River Lea. The historic rivalry with nearby Hertford can be traced to 1090 when the Lady of Ware (Petronilla de Grandmesnil, Countess of Leicester) diverted Ermine Street from the Roman ford to create a High Street and new bridge over the Lea. The bailiff of Hertford tried to destroy the new bridge before it was recognised as part of the King's Highway by Henry III in person. In 1381, during the so-called Peasants' Revolt, 42 prominent Ware townsmen, led by the Vicar, joined others in destroying Hertford Castle, then owned by John of Gaunt. Many inns were established in the High Street, reflecting Ware's importance as a coaching stop on the "Old North Road". Chaucer mentioned Ware twice in "The Canterbury Tales". The Great Bed of Ware, cited by Shakespeare and other playwrights, was housed in a succession of Ware inns.
