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.

Originating in late 18th-century Europe, feminist movements have campaigned and continue to campaign for women's rights, including the right to vote, run for public office, work, earn equal pay, own property, receive education, enter into contracts, have equal rights within marriage, and maternity leave. Feminists have also worked to ensure access to contraception, legal abortions, and social integration; and to protect women and girls from sexual assault, sexual harassment, and domestic violence. Changes in female dress standards and acceptable physical activities for women have also been part of feminist movements.

An organism's sex is female (symbol: ♀) if it produces the ovum (egg cell), the type of gamete (sex cell) that fuses with the male gamete (sperm cell) during sexual reproduction.

A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes (unlike isogamy where they are the same size).
