Tusweca Tiospaye was created in 2007 to combat the social problems facing the community, especially young people. Because of forced assimilation many had become disconnected from their Lakota language and culture.

Throughout the year as part of the Tusweca Tiospaye Lakota Dakota Nakota Language Summit, their work includes all Sioux reservations, reserves, and communities in the United States and Canada as well as participation and support from other tribes across Turtle Island (North America).

The Summit was created to unite the Seven Council Fires of the Great Sioux Nation in order to revitalize the language and culture. Much of the work is centered on the Pine Ridge Reservation including revitalizing the Lakota language, traditional songs and dances, games, foods, spirituality and culture programs.

The adult immersion program is one of their most recent programs designed to create second language adult speakers and give them the tools necessary to teach first language speakers in their households.
