What is the influence of early life trajectories, filled with experiences, encounters and emotions, on young to-be activists? Based on qualitative research done for the project "ArtCitizenship -youth and the arts of citizenship: creative practices, participatory culture and activism" (2019-2022), this article looks into individual trajectories, during childhood and youth, of 30 activists in Portugal. The collected data presents a set of "before activism" categories that reveal the importance of including early-life experiences to better understand future involvement with activism and social movements. One is not born an activist, actions for a given cause are a response to cumulative interactions and emotions felt from very early years.
