This chapter studies the entanglements of autobiographical writing with activism in the work of Hamed Farmand (1976–), an Iranian child rights activist who lives in the diaspora. Farmand spent five years of his childhood in 1980s Iran without his mother, who was a political prisoner during this period. As an adult, he began reflecting on this experience and writing about his life across different media, which gradually led him to become a child rights activist with a specific focus on the children of imprisoned parents. Farmand’s work, and its rootedness in lived experience, is of special importance in the Iranian context, where most types of activism are criminalised and many children endure the hardships of a tense political atmosphere. This chapter maps out Farmand’s trajectory from autobiographical writing to activism and demonstrates how, in his case, the formation of a child subject through continuous autobiographical practice has created a foundation for activism. Farmand’s case, as the chapter argues, exemplifies a productive practice of reframing a traumatic past into future-oriented activism by way of autobiographical practices.
