The Durbar Mahila Samanwaya Committee ( "Durbar Mohila Shômonbôe Shomiti" "Unstoppable Women's Synthesis Committee") or Durbar, is a collective of 65,000 sex workers in West Bengal. Established on 15 February 1992, in Sonagachi, the largest red-light district in Kolkata, West Bengal, India with estimated 11,000 sex workers, Durbar has been working on women's rights and sex workers' rights advocacy, anti-human trafficking and HIV/AIDS prevention. The Durbar states that its aims are the challenging and altering of the barriers that form the everyday reality of sex workers' lives as they relate to their poverty or their ostracism. Durbar runs 51 free clinics for sex workers across West Bengal, with support from organisations such as the Ford Foundation and the National AIDS Control Organisation (NACO), who also help Durbar in its initiatives like networking, rights protection and creating alternative livelihood for sex workers.
