Context paragraphs:
Native American peoples of Oregon: The Native American peoples of Oregon are the set of indigenous peoples who have inhabited or who still inhabit the area delineated in today's state of Oregon in the Pacific Northwest region of the United States.  While the state of Oregon currently maintains relations with nine federally recognized tribal groups, the state was previously home to a much larger number of autonomous tribal groups, which today either no longer exist or have been absorbed into these larger confederated entities.

Ngarrindjeri: The term Ngarrindjeri means "belonging to men".  and refers to a "tribal constellation".  They are the traditional Aboriginal people of the lower Murray River, western Fleurieu Peninsula, and the Coorong of southern, central Australia.  The Ngarrindjeri actually comprised several distinct if closely related tribal groups, including the Jarildekald, Tanganekald, Meintangk and Ramindjeri which began to form a unified cultural block after remnants of each separate community congregated at Point McLeay, now Raukkan.

Mangyan: Mangyan is the generic name for the eight indigenous groups found on the island of Mindoro, southwest of the island of Luzon, the Philippines, each with its own tribal name, language, and customs.  The total population may be around 280,000, but official statistics are difficult to determine under the conditions of remote areas, reclusive tribal groups and some having little if any outside world contact.

Ghegs: The Ghegs or Gegs (Albanian: "Gegët" ) are one of two major ethnic subgroups of Albanians (the other being the Tosks) differentiated by their cultural, linguistic, social and religious characteristics.  The Ghegs live in Albania (north of the Shkumbin river), Kosovo, Macedonia and Montenegro.  The name Gheg is derived from the term initially used by Orthodox population of pre-Ottoman Albania for confessional denotation when referring to their Catholic neighbors who converted to Catholicism to better resist the Orthodox Serbs.  The Ghegs speak Gheg Albanian, one of the two main dialects of Albanian language.  The social organization of the Ghegs was traditionally tribal, with several distinct tribal groups of Ghegs.

Ingaevones: The Ingaevones or North Sea Germanic peoples were a West Germanic cultural group living along the North Sea coast in the areas of Jutland, Holstein, Frisia and the Danish islands, where they had by the 1st century BCE become further differentiated to a foreigner's eye into the Frisii, Saxons, Jutes and Angles.

Pokanoket: The Pauquunaukit Wampanoag (anglicized as Pokanoket, literally, "land at the clearing" in Natick) is an indigenous group in present-day Rhode Island and Massachusetts.  Prior to European colonization, the Pokanoket were the leadership of the tribal groups that make up the modern-day Wampanoag Nation.  However, ethnically Pokanoket groups and their neighbors did not begin to refer to themselves as Wampanoag until after King Philip's War, when Pokanoket identity was criminalized in Rhode Island and Massachusetts.  Thus, while all Pokanoket are Wampanoag (being one tribe among several), not all Wampanoag are ethnically Pokanoket.  The Pokanoket are the indigenous group in the first Thanksgiving story, although it is speculated that no meal was actually shared between the Pokanoket and English settlers, and the former did not necessarily welcome colonization.

Istvaeones: The Istvaeones, also called Istaevones, Istriaones, Istriones, Sthraones, and Thracones, are mentioned as a Germanic tribal grouping in the writings of Tacitus and Pliny the Elder (~1st century AD).  They categorized them as one of the nations of Germanic tribes descended from one of the sons of Mannus, a Germanic ancestor.  The other two such peoples were the Ingvaeones and Irminones.

Tribals in Madhya Pradesh: There are 46 recognized Scheduled Tribes in Madhya Pradesh, India, three of which have been identified as 'Particularly Vulnerable Tribal Groups' (PTGs)(formerly known as 'Special Primitive Tribal Groups').  The population of Scheduled Tribals (ST) is 21.1% of the state population (15.31 million out of 72.62 million), according to the 2011 census.  Bounded by the Narmada River to the north and the Godavari River to the southeast, tribal peoples occupy the slopes of the region's mountains.

Samata (NGO): Samata is an India-based non-governmental organization that focuses on advocacy and development issues among tribal communities in Andhra Pradesh.  Samata helps tribal groups address problems of land alienation, displacement, and political dis-empowerment.  Its mission is to uphold the traditional, constitutional, and human rights of the tribal or adivasi people.

Morongo Band of Mission Indians: The Morongo Band of Mission Indians is a federally recognized tribe.  The main tribal groups are Cahuilla and Serrano.  Tribal members also include Cupeño, Luiseño, and Chemehuevi Indians.  Although many tribes in California are known as Mission Indians, some, like those at Morongo, were never a part of the Spanish Missions in California.  The Morongo Reservation is located in Riverside County, California.
