Uttar Pradesh in India is not a great place to be a woman. Quite the opposite in fact. The northern Indian state has high levels of violence against women, who are often failed by the police and the legal system leaving them waiting a long time for a fair trial and justice.

Tired of the poor justice system, Sampat Pal Devi founded the Gulabi Gang, an organisation that aims to challenge the deeply patriarchal structure of her society.

As a group that now boasts 400,000 women who wear pink saris and carry large sticks to beat offenders, they have not gone unnoticed and are making a mark in Northern India.
