Gathering and using information at the fifteenth-century Church councils: the example of crusade

Abstract

ABSTRACTThe discussion of crusade at the councils of Constance (1414–18) and Basel (1431–49) is used to test the hypothesis that in the fifteenth century increasing importance was attached to the gathering of information. At Constance the chief crusading topic was the past and future of the Baltic crusade; at Basel attention was given to the negotiation of peace with the Hussites and union with the Orthodox Greeks. The paper considers the origin and character of the information that reached the councils; how it was used in the discourse at Constance and Basel; and it then assesses the effect of information on collective decision-making at the councils. While it is only possible to see information exerting an impact in the case of peace with the Hussites, the overall value placed on it by the conciliar delegates was high, corroborating recent arguments that the fifteenth century was an ‘information age’.
