Biopolitics has played an important role in fascist totalitarianism and the-Francoist regime was no exception. From the and with ultimate goal or regulating the population, measures were implemented to increase, care for and indoctrinate the population. This present study analyses the selection and promotion measures of some populations and the marginalisation of others proposed the Spanish Falangist Movement's official publication in the field of medicine, the journal Ser, Revista Medico-Social by the National Delegation of Health of the Traditionalist Spanish Phalanx of the Committees of the National Syndicalist Offensivie (F.E.T y de las J. O. N. S. 1942-1957). In this respect, the analysis of eugenic ideas and practice defended therein become especially interesting, claiming that, through indoctrination and health development, the race would be improved both physically and mentally. From the systematic analysis of the journals's contenets it has been demonstrated that this was one of the instruments used by the dictatorial regime to reconfigure eugenics in accordance with Catholic morals and national syndicalist politics.
