La fabrique de la parenté à la fin du Moyen Âge : la construction d'une famille par Francesco Della Rovere – Sixte IV (1414-1484)

The kinship claimed by Francesco Della Rovere (1414-1484), who became pope under the name of Sixtus IV in 1471, does not seem to be based on biological criteria alone. On the contrary, it appears to be the fruit of a deliberate construction by the prelate, who assembles his family tree, branch by branch. This case study sheds light on the conception of kinship among the elites of the late Middle Ages. [Publisher's text]
