Nearly 25 years ago, some 30,000 women and men from nearly 200 countries arrived in Beijing, China for the Fourth World Conference on Women, determined to recognize the rights of women and girls as human rights. The conference culminated in the adoption of the Beijing Declaration and Platform for Action: the most comprehensive policy agenda for the empowerment of women. In the years following, women pressed this agenda forward, leading global movements on issues ranging from sexual and reproductive health rights to equal pay. More girls today are attending and completing school, fewer are getting married or becoming mothers while still children, and more are gaining the skills they need to excel in the future world of work. Today, these movements have expanded. They are being organized by and for adolescent girls, and tackling issues like child marriage, education inequality, gender-based violence, climate change, self-esteem, and girls’ rights to enter places of worship or public spaces during menstruation. Girls are proving they are unscripted and unstoppable. This year, under the theme, “GirlForce: Unscripted and unstoppable”, we will celebrate achievements by, with and for girls since the adoption of the Beijing Declaration and Platform for Action.
