The National Slum Dwellers Federation (NSDF) in India was established by Jockin Arputham when he fought on behalf of a community of 70,000 to appeal a 1976 eviction order.
It is a national organization which brings together multiple communities and their leaders who live in slum settlements around India.
Due to the efforts of NSDF, around 90 buildings and 300 toilet blocks have been constructed in Mumbai, providing houses and sanitation to over 35,000 families.
By 1970, Jockin was travelling all around Mumbai and India to meet other slum leaders and dwellers to help fight the eviction order.
Yet, due to the National Emergency declared by Indira Gandhi, fresh eviction orders were given and an arrest warrant for the slum leaders was also issued.
