## Research and publications

Bisson's research lies in the fields of history and medieval studies with its focus on the cultural history of power in medieval Europe, particularly France and Catalonia, in the post-Carolingian period (A.D. 950 - 1250). In addition to articles, his publications include books, among them Conservation of Coinage: Monetary Exploitation and its Restraint in France, Catalonia, and Aragon (c.A.D.1000-c.1225); The Medieval Crown of Aragon: A Short History, a survey of medieval Catalonia during the centuries when it was ruled by kings of Aragon; an edited collection of studies by other historians entitled Cultures of Power: Lordship, Status, and Process in Twelfth-Century Europe. His course in Harvard's Core program, offered in 1988, 1990, 1993, 2001, 2003, became a book entitled The Crisis of the Twelfth Century: Power, Lordship, and the Origins of European Government. In a review for the New York Review of Books, Robert Bartlett contended that this was a book about government, after all, but in his rebuttal, Bisson insisted on his own distinction, rooted in the sources, between power and government. His edition of the Fiscal Accounts of Catalonia, led to his book Tormented Voices: Power, Crisis, and Humanity in Rural Catalonia, 1140–1200, which explored peasants' voices from Catalan villagers revealing their grievances against the Count of Barcelona's agents, shedding light on ambitions to power amongst non-nobles in castles, as Margaretta S. Handhe stated, "Using excellent prose and interpretive skill, Bisson has rescued these peasants from anonymity and given their sufferings a life beyond their mortal existence." Of his latest book, The Chronography of Robert of Torigni, 2 vols., Sean McGlynn wrote, "Bisson's masterful new edition is clearly to be considered as the new gold standard."
Bisson's article "The 'Feudal Revolution" defended Marc Bloch and Georges Duby, French historians who had demonstrated a massive societal transformation in the eleventh and twelfth centuries, when lords, fiefs, and vassals multiplied. In his presidential address to the Medieval Academy of America (1995), he pointed out that lords and lordships had multiplied exponentially after about 990. This entailed a breakdown of public order, the rise of new lordships amongst the men of castles in the quest of nobility, the loss of civic or official identities, and while he had first studied precedents for parliamentary representation in the thirteenth century, his later books and teaching stressed the importance of public interest as a new and debatable concept essential to government, however minimal, and first perceptible in Catalonia and England in the years from about 1180 to 1215. As he first argued in The Crisis of the Twelfth Century, there were notable precedents for official order, with new forms of accountability arising in France, the Low Countries, and England even as accountable agents, such as sheriffs continued to behave like lords in quest of noble status. In another study Pouvoir et consuls à Toulouse (1150-1205), he showed that elected consuls themselves were striving for lordly status.
