In 2001, over 25,000 sex workers gathered in India for a festival, despite efforts from prohibitionist groups who tried to prevent it taking place by pressuring the government to revoke their permit. The event was organised by Durbar Mahila Samanwaya Committee, a Calcutta based group that has over 50,000 sex worker members, and members of their communities. Sex worker groups across the world have subsequently celebrated 3 March as International Sex Workers’ Rights Day.
