The theme of the exhibition paraphrases the title of Engels' well-known book "The Origin of the Family, Private Property and the State". In the context of research on contemporary photography, these terms summarize some of the most important narratives in today's photographic work. Probably a large part of the connotations of the concept of the archive in contemporary photographic practices is related to two fundamental figures: the Family and the State. One of the dominant narratives in contemporary photography revolves around the theme of the family.

It seems that the family is a pretext to approach intergenerational friction from photography and that photography is in turn a pretext to account for the changes that the concept of family itself has undergone, as well as its symbolic implications. Beyond the sentimentality with which the experience of the loss of loved ones is often assumed, the representations of the family in contemporary photography tend to have a serious tone, close to mourning and nostalgia. His imaginary is full of remembrances and absences, although it also includes a critical, sometimes ironic, review of traditional discourses on the "fundamental cell of society", as well as the rituals in which these discourses are sustained and the ideological plots that interweave. The place of photography in these rituals has been decisive in its cultural impact since the 19th century to date.

As an anthology of the representations of the family, this exhibition becomes an investigation into the representations of the private space, habits, relations with property and the State, as well as the various social roles, according to class, gender or race.
