In 1995 at the World Conference on Women in Beijing countries unanimously adopted the Beijing Declaration and Platform for Action – the most progressive blueprint ever for advancing the rights of not only women but girls. The Beijing Declaration is the first to specifically call out girls’ rights.

On December 19, 2011, United Nations General Assembly adopted Resolution 66/170 to declare October 11 as the International Day of the Girl Child; to recognize girls’ rights and the unique challenges girls face around the world.

The International Day of the Girl Child focuses attention on the need to address the challenges girls face and to promote girls’ empowerment and the fulfilment of their human rights.

Adolescent girls have the right to a safe, educated, and healthy life, not only during these critical formative years, but also as they mature into women. If effectively supported during the adolescent years, girls have the potential to change the world – both as the empowered girls of today and as tomorrow’s workers, mothers, entrepreneurs, mentors, household heads, and political leaders. An investment in realizing the power of adolescent girls upholds their rights today and promises a more equitable and prosperous future, one in which half of humanity is an equal partner in solving the problems of climate change, political conflict, economic growth, disease prevention, and global sustainability.

Girls are breaking boundaries and barriers posed by stereotypes and exclusion, including those directed at children with disabilities and those living in marginalized communities. As entrepreneurs, innovators and initiators of global movements, girls are creating a world that is relevant for them and future generations.

This year’s theme  is "Ending child marriage and investing in girls' rights" and was developed through consultations with girls, girls’ organizations and girl-led networks as well as civil society organizations and United Nations partners.

Every girl deserves a childhood. Every girl deserves the freedom to learn, to grow, to make her own choices and to define her own future. Yet millions of girls are still denied that freedom.
