Feminism is a collection of movements and ideologies aimed at defining and establishing equal political, economic, and social rights for women. It has occurred in three waves, focusing on women's suffrage, gender equality, and continued issues of oppression, respectively. Feminism explores the interconnected nature of concepts like patriarchy, sexism, and women's status globally that contribute to women's inequality. It aims to challenge these systems through perspectives like liberal, radical, socialist, and postcolonial feminism.
