The book "Subjugation of Women" is a revolutionary treatise by the outstanding English philosopher and politician John Stuart Mill, in which he expresses his belief in the inherent equality of the rights of men and women in society. The author analyzes the patriarchal system, which limits the rights and opportunities of women, and calls for changes in the social system to achieve justice and equality between the sexes. The book became an important source for the feminist movement and influenced the development of gender theory. It remains relevant to this day, prompting readers to discuss issues of gender equality and human rights.
