Research shows that quotas and feminist movements impose gender mandates on congresswomen, shaping their legislative outputs. However, this scholarship treats women as a homogeneous collective, rendering invisible intragroup differences. This article addresses this gap by asking how gender quotas shape the representation of marginalized women’s interests in contexts characterized by strong gender mandates. Analyzing the Chilean case, I compared the legislative terms pre (2014–18) and post (2018–22) quota. First, I examined how many marginalized women entered Congress in each cycle. Then, I reviewed the contents of all laws and bills on gender issues and marginalized groups sponsored by the congresswomen, to determine how well they represented marginalized women’s needs. Finally, I analyzed who were the main sponsors of intersectional legislation. The findings indicate that marginalized women’s interests, though better represented after the quota implementation, remained a marginal portion of congresswomen’s legislative output.
