City of Southampton: History
=== Pre-Norman ===
Archaeological finds suggest that the area has been inhabited since the Stone Age. Following the Roman invasion of Britain in AD 43 and the conquering of the local Britons in AD 70 the fortress settlement of Clausentum was established. It was an important trading port and defensive outpost of Winchester, at the site of modern Bitterne Manor. Clausentum was defended by a wall and two ditches and is thought to have contained a bath house. Clausentum was not abandoned until around 410.
The Anglo-Saxons formed a new, larger, settlement across the Itchen centred on what is now the St Mary's area of the city. The settlement was known as Hamwic, which evolved into Hamtun and then Hampton. Archaeological excavations of this site have uncovered one of the best collections of Saxon artefacts in Europe. It is from this town that the county of Hampshire gets its name.
Viking raids contributed to the decline of Hamwic in the late 9th century, and by the 10th century a fortified settlement, which became medieval Southampton, had been established.
Following the Norman Conquest in 1066, Southampton became the major port of transit between the then capital of England, Winchester, and Normandy. Southampton Castle was built in the 12th century and surviving remains of 12th-century merchants' houses such as King John's House and Canute's Palace are evidence of the wealth that existed in the town at this time. By the 13th century Southampton had become a leading port, particularly involved in the import of French wine in exchange for English cloth and wool.
The Franciscan friary in Southampton was founded circa 1233. The friars constructed a water supply system in 1290, which carried water from Conduit Head (remnants of which survive near Hill Lane, Shirley) some 1.1 mi (1.7 km) to the site of the friary inside the town walls. Further remains can be observed at Conduit House on Commercial Road. The friars granted use of the water to the town in 1310.
Between 1327 and 1330, the King and Council received a petition from the people of Southampton. The community of Southampton claimed that Robert Batail of Winchelsea and other men of the Cinque Ports came to Southampton under the pretence that they were a part of Thomas of Lancaster's rebellion against Edward II. The community thought that they were in conspiracy with Hugh le Despenser the Younger. The petition states that, the supposed rebels in the Despenser War 'came to Southampton harbour, and burnt their ships, and their goods, chattels and merchandise which was in them, and carried off other goods, chattels and merchandise of theirs found there, and took some of the ships with them, to a loss to them of £8000 and more.' For their petition to the King somewhere after 1321 and before 1327 earned some of the people of Southampton a prison sentence at Portchester Castle, possibly for insinuating the king's advisor Hugh le Despenser the Younger acted in conspiracy with the Cinque Port men to damage Southampton, a flourishing port in the fourteenth century. When King Edward III came to the throne, this petition was given to the king and his mother, Queen Isabella, who was in charge of the town, and the country at this stage likely organised the writ of trespass that took any guilt away from the community at Southampton. …
