The main purpose of this article is to re-examine the legacy of Marx and Simmel for the study of romantic love from a feminist perspective. I am interested in the relational legacy these two authors provide for the study of the affective sphere. Specifically, I am interested in highlighting how both offer analytical inputs to consider the relationships between love, power, and conflict. I attempt to answer the following questions: What do Marx and Simmel postulate when they talk about love? What is the complementary contribution of their proposals considering recent studies on love from a feminist perspective? While Marx allows us to incorporate the socio-structural and historical level -specifically the material dimension -, Simmel allows us to incorporate the social process and symbolic exchange -specifically the cultural dimension -to think about the affective dimension of social ties and love as social bond. I consider that from this analytical and political perspective, the Marxist-Simmelian legacy provides a thought-provoking program for the relational analysis of affects, emotions and love.
