El Sistema Patriarchal refers to a societal structure where men hold primary power and dominate roles in leadership, moral authority, social privilege, and control of property. This system often results in the systematic oppression of women, reinforcing gender inequalities that permeate various aspects of life, including cultural, political, and economic spheres. In the context of Julia de Burgos's work, this term highlights the struggles and constraints faced by women within a male-dominated society.
