Abstract
This paper analyzes canon 3 of the council of Pisa of 1135, with which the trade in persons is prohibited, pointing out that this prohibition must be considered valid also for the sale of inhabitants of Corsica, be they men or women. After having drawn up a general overview of the council, it will focus on the text of the third canon to understand the reasons that led the council fathers to deal with the subject of slavery, firmly defending the Corsican population, considered as a “minority” victim of a political and economic system. As we will try to show, the text of this canon is a unicum of its kind and is fully inserted within the panorama of the Church’s teaching on the subject of slavery, adding a new piece to the mosaic of what was already known about the work of the ecclesiastical institution on this subject.
