This paper aims to contribute to discussions around alliances and collaborations between feminisms. It analyses relations between movements in the development of indigenous women's organizational autonomy in Mexico. It seeks to understand how the struggle for autonomy involved a redefinition of the forms of collaboration by indigenous women in the consolidation of their movement. An intersectional perspective is proposed to better understand how power relations affect the organizing processes of social movements, as well as how organizations and individuals respond to and challenge them. I argue here that the redefinition of collaborations and alliances has been a key determinant in the organizing capacity of indigenous women to position themselves as autonomous political actors. From the analysis of two specific cases, this paper poses broader questions regarding representation and autonomy that may be applied towards a reflection of our feminist practices and discourses of solidarity.
