The goal of this study was to examine the causes of child marriage in Ethiopia from the feminist perspectives of liberalism, radicalism, and socialism. The theoretical framework is based on liberal, radical, and socialist feminism perspectives, which are divided into six key components. Equal access to society, state governance, patriarchy, social norms, class divisions, and economic differences are among them. A case study was used as a method to answer the study's research topic. The analysis used the essential components to explain the causes of child marriage in Ethiopia. When looking at Ethiopia through the lens of these three feminist perspectives, the findings reveal that there exist gender inequalities related to child marriage. The practice of child marriage in Ethiopia has been demonstrated to be influenced by women's access to society, state governance, women's value, social norms, poverty, and economic disparities between men and women.
