In previous research, little work was done to understand how and to what extent female combatants in Colombian revolutionary groups functioned as leaders. This paper seeks to assess the agency that women in Colombian leftist revolutionary organizations such as M-19 and FARC had access to, specifically with regards to leadership. Colombian revolutionary groups failed to successfully incorporate women into higher ranks, despite claiming otherwise. The military structure particularly favors men by esteeming masculine roles and blaming women for the transgressions of men. This paper specifically evaluates the differences between the M-19 and FARC with regards to female leadership. The M-19 more effectively incorporated women into leadership roles than FARC due to differences regarding representation.
