What social characteristic did Wollstonecraft challenge in her works?

Wollstonecraft challenged gender inequalities primarily through her seminal work, "A Vindication of the Rights of Woman," where she argued for women's access to education and their rightful place in society, advocating for equality between the sexes. She highlighted how society's treatment of women manifested as a form of oppression, emphasizing that women should not be confined to roles that limit their potential or deny them independence and rational thought.

While other social characteristics such as hierarchy of social classes, economic systems, and religious beliefs are important, Wollstonecraft’s focus was distinctly on the inequalities faced by women and the societal structures that perpetuated these inequalities. Her arguments were foundational to feminist thought, which sought to dismantle patriarchal systems and promote the idea that women deserve the same rights and opportunities as men.
