They are the second largest tribal group in North-East India, first being the Bodos in NorthEast.  They were earlier called Miris in historical days.  and the Constitution of India still refers to them as Miris.  MIRI is the ancient name and traces back to the ancestor ABO TANI. The Ramapough Mountain Indians (also spelled Ramapo), also known as the Ramapough Lenape Nation or Ramapough Lunaape Munsee Delaware Nation, are a group of approximately 5,000 people living around the Ramapo Mountains of Bergen and Passaic counties in northern New Jersey and Rockland County in southern New York, about 25 miles (40 km) from New York City.  They were recognized in 1980 by the state of New Jersey as the Ramapough Lenape Nation but are not federally recognized.  Their tribal office is located on Stag Hill Road on Houvenkopf Mountain in Mahwah, New Jersey.  Since January 2007, the chief of the Ramapough Lenape Nation has been Dwaine Perry. John Copp (June 9, 1673 – May 16, 1751) was a member of the House of Representatives of the Colony of Connecticut from Norwalk in the sessions of May 1706, May 1716, October 1718, and May 1719.  He served from 1708 to 1740 as the town clerk of Norwalk.  He was one of the purchasers of the land for the present town of Ridgefield, Connecticut from the Ramapoo Indians, as well as the town's clerk and surveyor.  He also laid out the lots and roads of the present town of Bedford, New York. Culture of Tripura is similar to those of Native indigenous tribal peoples of Northeast India.  However like Assam, Manipur, Burma and Southeast Asia culture of Tripura is characterized in small portion living in plain areas by mainstream Indian cultural influence spearheaded by Bengali culture coexisting with tribal traditional practices specially living in those plain areas, not much extending to Hill people of Tripura notably the Tripuri culture.  Tripura is a state in North East India.  In the 2001 census of India, Bengalis represented almost 70% of Tripura's population and the tribal population comprised 30% of Tripura's population.The tribal population comprises several different tribes and ethnic groups with diverse languages and cultures.  The largest tribal group was the Kokborok-speaking tribe of the Tripuri who had a population of 543,848 in 2001 census, representing 16.99% of the state population and 54.7% of the scheduled tribe population.  The other major tribes in order of decreasing population were Reang (16.6% of the tribal population), Jamatia (7.5%), Chakma (6.5%), Halam (4.8%), Mog (3.1%), Munda, Kuki tribes and Garo.  Bengali is the most spoken language, due to the predominance of Bengali people in the state.  Kokborok is a prominent language among the tribes.  Several other languages belonging to Indo-European and Sino-Tibetan families are spoken by the different tribes. Particularly vulnerable tribal group (PVTG) (earlier: Primitive tribal group) is a government of India classification created with the purpose of enabling improvement in the conditions of certain communities with particularly low development indices.

Kiskiack (or Chisiack or Chiskiack) was a Native American tribal group of the Powhatan Confederacy in what is present-day York County, Virginia.  The name means "Wide Land" or "Bread Place" in the native language, one of the Virginia Algonquian languages.  It was also the name of their village on the Virginia Peninsula. Gilead was a tribal group mentioned in Biblical passages which textual scholars attribute to early sources.  In these sources, for example the Song of Deborah, the Gilead group is treated with equal status to the other Israelite tribes, while certain other tribes, including the Tribe of Manasseh, are absent.  An eponymous "Gilead" is mentioned in the biblical genealogies as a descendant of Manasseh, presumably implying that the "Gilead" group was part of Manasseh, and since "Gilead" is also the name of a specific part of the land east of the Jordan River, the "Gilead" tribal group presumably refers to the "half tribe" of Manasseh which resided on this side of the Jordan.  The identity as part of a single tribe named "Manasseh", doesn't appear to have been fully accurate in practice, since there was very little geographic connection between the two "half tribes", only just touching at a corner of each, and according to the Book of Chronicles each "half tribe" historically had always had separate tribal rulers. Improvisational Tribal Style (ITS) belly dance, or ITS, is a combination-based form of Improvisational "Tribal Fusion" dance.  It relies on a shared vocabulary of movements, each initiated by a distinct cue movement.  The leader initiates the cue movement, then a short, choreographed combination, or Combo, is performed.  These Combos can be done in any order, and none of the dancers know ahead of time what moves the leader will cue next.  Improvisational Tribal Style is a specific style or school of Tribal bellydance.  The term was first coined in 2006 by Amy Sigil of UNMATA to describe her Improv vocabulary, as it evolved away from ATS American Tribal Style.  (Similar styles include American Tribal Style, Synchronized Group Improv, Tribal Group Improv, American Improv Tribal, Group Improv Tribal.)
