The Romans invaded Britain again in 43 CE, and Hampshire was incorporated into the Roman province of Britannia very quickly. It is generally believed their political leaders allowed themselves to be incorporated peacefully. Venta became the capital of the administrative polity of the Belgae, which included most of Hampshire and Wiltshire and reached as far as Bath. Whether the people of Hampshire played any role in Boudicca's rebellion of 60–61 is not recorded, but evidence of burning is seen in Winchester dated to around this period. For most of the next three centuries, southern Britain enjoyed relative peace. The later part of the Roman period had most towns build defensive walls; a pottery industry based in the New Forest exported items widely across southern Britain. A fortification near Southampton was called Clausentum, part of the Saxon Shore forts, traditionally seen as defences against maritime raids by Germanic tribes. The Romans withdrew from Britain in 410.
