the Hallaton Treasure, was found at a Late Iron Age shrine near Hallaton, Leicestershire, in 2000 and consisted of 5,294 coins, mostly attributed to the Corieltavi tribe. These were buried in 14 separate hoards over several decades in the early 1st century AD. The expansion of the economy throughout the period, but especially in the later Iron Age, is in large part a reflection of key changes in the expression of social and economic status. Trade Early and Middle Iron Age The Early Iron Age saw a substantial number of goods belonging to the Hallstatt culture imported from the continent, and they came to have a major effect on Middle Iron Age native art. Late Iron Age From the late 2nd century BC onwards, South-Central Britain was indirectly linked into Roman trading networks via Brittany and the Atlantic seaways to south-western Gaul. Hengistbury Head in Dorset was the most important trading site, and large quantities of Italian wine amphorae have been found there. These Atlantic trade networks were heavily disrupted following Julius Caesar's failed conquest of Brittany in the 50s BC. This fact may support a supposition that the Celts of Britain had an economic interest in supporting their Gallic brethren in their resistance to Roman occupation. In South-eastern Britain, meanwhile, extensive contact with the 'Belgic' tribes of northern Gaul is evidenced by large numbers of imported Gallo-Belgic gold coins between the mid-2nd century BC and Caesar's conquest of Gaul in the 50s BC. Those coins probably did not principally move through trade. In the past, the emigration of Belgic peoples to South-Eastern Britain has been cited as an explanation for their appearance in that region. However, recent work suggests that their presence there may have occurred from a kind of political and social patronage that was paid by the northern Gaulish groups in exchange for obtaining aid from their British counterparts in their warfare with the Romans on the Continent. After Caesar's conquest of Gaul, a thriving trade developed between South-Eastern Britain and the near Continent. That is archaeologically evidenced by imports of wine and olive oil amphorae and mass-produced Gallo-Belgic pottery. Strabo, writing in the early 1st century AD, lists ivory chains and necklaces, amber gems, glass vessels and other petty wares as articles imported to Britain, and he recorded the island's exports as grain, cattle, gold, silver, iron, hides, slaves and hunting dogs. That trade probably thrived
