The paper takes up a problem which has not been sufficiently studied by Spanish classical scholarship, that of the Romans' relations with the Iberians during the conquest of the Iberian Peninsula. The author examines the data of written sources on killing the enemy, on enslaving them, on hostages, taxation, taking over the enemies' land, selling their property etc., describ-ing the peculiarities of these forms, the circumstances in which they could be resorted to and their consequences. All these aspects are analysed in order to find out whether there was a definite paradigm of conduct of the Romans during the subjugation of Spain, and if there was, what its essence was and how dynamic and efficient it turned out to be.
