Hitchin is a market town in the North Hertfordshire District in Hertfordshire, England.
Hitchin is first noted as the central place of the Hicce people mentioned in a 7th-century document, the Tribal Hidage. The tribal name is Brittonic rather than Old English and derives from *siccā, meaning 'dry', which is perhaps a reference to the local stream, the Hiz. It has been suggested that Hitchin was the location of 'Clofeshoh', the place chosen in 673 by Theodore of Tarsus the Archbishop of Canterbury during the Synod of Hertford, the first meeting of representatives of the fledgling Christian churches of Anglo-Saxon England, to hold annual synods of the churches as Theodore attempted to consolidate and centralise Christianity in England.
By 1086 Hitchin is described as a Royal Manor in Domesday Book: the feudal services of Avera and Inward, usually found in the eastern counties, especially Cambridgeshire and Hertfordshire, were due from the sokemen, but the manor of Hitchin was unique in levying Inward. Evidence has been found to suggest that the town was once provided with an earthen bank and ditch fortification, probably in the early tenth century but this did not last. The modern spelling 'Hitchin' first appears in 1618 in the "Hertfordshire Feet of Fines".
