This paper explores the roles of museums as social actors in promoting substantive equality and protecting international human rights, focusing on the experience of women from marginalized communities. Museums are places where the past meets the present. They are considered guardians of cultural heritage, educators, and moderators. Accordingly, their primary role should be to assist in social cohesion and intercultural dialogue. Despite this, museums continue to foster the same homogenous systemic cultural patterns. While they have been implementing various programs for diversity and inclusion for several years, these efforts are not enough. Most museums continue to follow very strict, traditional rules and procedures, even those that are considered “modernized,” reinforcing patterns of systemic discrimination. Most museums are still struggling to redefine themselves as separate from the stereotypical patriarchal patterns. One of the consequences is that there are more artworks in museums focused on women’s bodies than the creative outputs of female authors. This is particularly true when examining the involvement and presence of women from marginalized communities in the work of these institutions. Furthermore, women with multiple intersecting identities get less representation, while those from transgender and non-binary communities are almost non-existent in museums. There are only a few examples of their inclusion, mostly in developed countries. How can we reclaim and redefine museums as inclusive public spaces? Are museums obliged to serve as actors of social progress? How can they enforce substantive equality and equity? This paper will analyze how the intersectional human rights approach can promote and foster the inclusion and full participation of women from marginalized communities in public spaces such as museums.
