The Schaghticoke Tribal Nation has sought federal recognition since 1981. In 1986, a splinter group split off from STN and is known as the Schaghticoke Indian Tribe. Both STN and SIT are state-recognized in Connecticut, but not federally recognized. STN was granted federal recognition in 2004. However, federal recognition was revoked in 2005. STN has pursued restoration of their federal recognition. In 2015, STN was informed by the Bureau of Indian Affairs that they could not re-petition for federal recognition.
