Our survey revealed very few sites belonging to the Early Medieval period (AD 700-1000) apart from Tuscania, indicating a combination of population decline and abandonment of the countryside for the security of the town. There was significant demographic growth in the High Medieval period (AD 1000-1200): 38 sites, together with 30 sites with ‘generic Medieval’ material likely to belong to this phase. The new foundations, distributed throughout the survey area, comprised nucleated but unfortified settlements, a habitation form about which the documentary record is largely silent. In the Late Medieval period (AD 1200-1500: 16 sites), new foundations were established within a few kilometres of Tuscania with little evidence for settlement in the countryside beyond. Most farmers preferred to live in defensible castelli, or within the vicinity of Tuscania. As elsewhere in Italy, the second half of the 2nd millennium has witnessed the increasing abandonment of many small farms by peasant (contadini) families in the face of urban growth and industrialization, with globalization in recent decades accelerating their replacement and absorption by agribusinesses, and the flight to the countryside by middle class commuters from Rome.

The survey indicates marked continuity in rural settlement around Tuscania from Etruscan times into Roman Early Republican period (c.300-170 BC: 212 sites), implying that there was minimal disruption to pre-existing systems of ownership following the subjugation of the area by the Roman army. There was a dramatic expansion in rural settlement, a filling-up of the countryside particularly in formerly under-developed areas away from the town. This growth was encouraged by a better communications network, especially by the upgrading of the Via Clodia.There were increased levels of investment both in the town and in the surrounding countryside. Maximum site numbers developed in the Later Republican period (170-30 BC: 230 sites), and on the evidence of intensive grid collection of surface remains at selected sites, and geophysical survey at others, the core buildings of agrarian units first reached their maximum extent at this time. However, there is little evidence for large slave-run villas producing goods geared primarily for export and displacing the free peasantry, despite the written sources emphasizing this process throughout Italy at this time: the countryside around Tuscania was dominated by small farms and villages, and high-ranking sites did not bring significant changes to long-established farming regimes.

Before our project Etruscan Tuscania was best known for its great family tombs with inscribed sarcophagi of the 4th-2nd centuries BC, but the survey evidence shows that the Etruscan landscape was most densely settled in the 6th century BC (219 sites), coincident with the process of urbanization. The frequency of ‘off-site’ material indicates that Etruscan agricultural activity extended over the greater part of the surveyed area. Little survives of the remains of the Etruscan town, but the richness of Etruscan material immediately south of the city walls indicates a suburban extension of it. The development of Tuscania implies that the control of minor centres by major centres (or rather, the control of less powerful by more powerful families as social and economic inequalities became increasingly marked) was one of the earliest features of Etruscan urbanization. The Archaic Etruscan phase was followed by a marked, though not dramatic, population decline in the Later Etruscan phase (129 sites), the fifth and fourth centuries BC. Activities at Guidocinto, a small but long-lived Etruscan farm we excavated near Tuscania, included the production and processing of oil, wine, and wool, products that enhanced elite lifestyles and provided them with valuable resources for exchange and trade.

The project’s results indicate that a landscape once dominated by small, family-run, farms, each cultivating small plots of land, gradually transformed through the three phases of the Roman imperial period (Early, 30 BC-AD 120: 205 sites; Mid, AD 120-260: 174 sites; Late, AD 260-440: 146 sites) into one featuring large agricultural estates involved in extensive farming practices. In light of historical records it seems likely that affluent investors bought up much of the land of failing smallholders, expanding the capacity of their own agricultural enterprises and leasing out properties to poorer farmers. Local wealth, power, and influence became concentrated in the hands of a limited number of elite landowners. Yet despite this process, small low-status sites remained the most abundant class of rural habitation even in the Late Imperial period and many middle-ranking sites endured without a break in occupation even into Late Antique times (AD 440-700: 77 sites in total). The resilience of wide sections of the rural community, even in the face of external threats from Longobards and others, should not be underestimated, but significantly a considerable proportion of Tuscania’s hinterland of cultivated fields had reverted to scrub and woodland by the Late Antique period.
