Protofeminism is a concept that anticipates modern feminism in eras when the feminist concept as such was still unknown. This refers particularly to times before the 20th century, although the precise usage is disputed, as 18th-century feminism and 19th-century feminism are often subsumed into "feminism". The usefulness of the term protofeminist has been questioned by some modern scholars, as has the term postfeminist.

Feminism is a range of socio-political movements and ideologies that aim to define and establish the political, economic, personal, and social equality of the sexes. Feminism holds the position that modern societies are patriarchal—they prioritize the male point of view—and that women are treated unjustly in these societies. Efforts to change this include fighting against gender stereotypes and improving educational, professional, and interpersonal opportunities and outcomes for women.
