text: In the western Terai, many Tharu families lost the land, which they used to cultivate, to these immigrants and were forced to work as Kamaiya.
  In Chitwan, after the eradication of malaria, the U.S. government joined forces with the Nepali government in a project to build a new road, schools and health clinics, and distribute land to migrants from the hills. They invited Tharu people to take land but many Tharus preferred staying "voluntarily landless", as they worried that taking land would make them vulnerable to exploitation from Nepali governmental tax collectors and to attacks from wild animals. They preferred to stay as tenants for large Tharu landlords, who were often relatives.
  When the first protected areas were established in Chitwan, Tharu communities were forced to relocate from their traditional lands. They were denied any right to own land and thus forced into a situation of landlessness and poverty. When the Chitwan National Park was designated, Nepalese soldiers destroyed the villages located inside the national park, burned down houses, and beat the people who tried to plough their fields. Some threatened Tharu people at gun point to leave.
  1990 to present
  After the overthrow of the Panchayat system in Nepal in 1990, the Tharu ethnic association Tharu Kalyankari Sabha joined the umbrella organisation of ethnic groups, a predecessor of the Nepal Federation of Indigenous Nationalities.
