'Medieval Rome' analyses the history of the city of Rome between 900 and 1150, a period of major changes in the city. It takes the urban economy, the social history of the different strata of society, the articulation between the city's regions and the cultural identity of Rome as seen in its processions, its material culture, its legal transformations and its sense of the past. These are the underpinnings of a major reinterpretation of the city's political history in the era of the 'reform papacy', one of the greatest crises in Rome's history.
