This paper presents a political reflection on the documentation and recording of information about human rights activism in Mexico, particularly the struggle for territory, the environment, civil rights, LGBTTIQ+ community, disappeared persons, etc. The List of Spanish Wikipedia entitled 'Anexo:Activistas asesinados en México (Activists murdered in Mexico)' is the central space of the analysis, and from this we will show the importance of the documentation of journalistic and academic research that become central sources that nourish a recent tragic memory.
