Friendship is a form of interpersonal relationship present in the most diverse cultures and evident throughout the history of humanity. Some classical psychology theorists, such as Freud and Jung, although they do not address it directly, point out important issues in this area for human development, identity formation and the socialization process. When dealing with women, it can transcend its relevance, involving aspects that strengthen identity and the fight for rights and equality. To develop this article, a brief bibliographical research was carried out, with the objective of developing a dialogue on the importance of friendship between women for strengthening feminist ideals and female subjectivities, in the face of a structurally sexist culture. The research showed, through the example of friendships such as those between singer Nina Simone and playwright Lorraine Hansberry, pioneers of black feminism and activists for the civil rights of black Americans in the 1960s, that fraternal bonds can be transformative, liberating and strengthening of the gender and racial identity of those who enjoy them. The feminist movement, which began in the 1980s, is an example of fraternity that translates into strength, by uniting women around issues that emancipate and empower them in the face of the challenges and oppression of an unequal world.
