The paper is directed towards the wider background of false documents in the middle ages. The emphasis is placed on false documents that originated in the environment of the medieval ecclesiastical elites. The study considers the motives of medieval falsifiers, but the author places in the foreground the question of the ways false documents were seen or the reasons leading to the high level of spreading of false documents in the middle ages. The paper is written as a widely conceived account reflecting the observations of medievalists concerned with the problem of falsified documents. At the same time, increased emphasis is placed in the circumstances in which documents were falsified in the oldest monastic or specifically Benedictine environment of Hungary under the Arpád dynasty.
