Big Tree (or The Big Tree in Chirinda Forest) is the tallest native or indigenous tree in Zimbabwe, and a declared National Monument.
 The tree is 65 m tall and measures 4.5 m in diameter, while its age is estimated at 1,000 years or over.
 This impressive tree is growing in the centre of the Chirinda Forest (formerly known as Selinda, from the Mount Selinda Mission School of the same name) in the south east of Zimbabwe at the southernmost part of the country's Eastern Highlands.
 Big tree is a "Khaya anthotheca" or Nyasa redwood tree (also referred to previously as "Khaya nyasica").
 In December 1986 it was measured at 65 metres tall and 5 1/4 metres in diameter.
 The trunk is very heavily and hugely buttressed at the base that makes measuring difficult.
Big Tree (Kiowa: Ado-ete (unknown c. 1845–1930)), was a war chief of the Kiowa.
 He was a loyal follower of the fighting chiefs party (Satank, Satanta, Guipago), and conducted frequent raids upon other tribes and white settlers, often being associated with Tsen-tainte (“White Horse”).
White Horse (Kiowa: Tsen-tainte, unknown c. 1840/1845–1892) was a chief of the Kiowa.
 White Horse attended the council between southern plains tribes and the United States at Medicine Lodge in southern Kansas which resulted in the Medicine Lodge Treaty.
 Despite his attendance at the treaty signing he conducted frequent raids upon other tribes and white settlers.
 Follower of such elder chiefs as Guipago, Satanta and old Satank, he was often associated with Big Tree (or "Ado-ete"), this one too a young war leader in the Kiowa nation.
The Tonkawa are a Native American tribe indigenous to present-day Oklahoma and Texas.
 They once spoke the now-extinct Tonkawa language; it is believed to have been a language isolate not related to any other indigenous tongues.
 Today, many descendants are enrolled in the federally recognized tribe Tonkawa Tribe of Indians of Oklahoma.
The Webster/Dudley Band of the Chaubunagungamaug Nipmuck Indians, also known as the Chaubunagungamaug, Chaubunagungamaug Nipmuck, Pegan or Dudley Indians, are a Native American tribe indigenous to the U.S. states of Massachusetts and Connecticut in the region of New England.
 They are one of three tribes with state recognition in Massachusetts as a tribe of Nipmuck Indians, including the Hassanamisco Nipmuc and the Natick Massachusett, although the latter are mainly descended from the Massachusett people.
Plains Indians, Interior Plains Indians or Indigenous people of the Great Plains and Canadian Prairies are the Native American tribes and First Nation band governments who have traditionally lived on the greater Interior Plains (i.e. the Great Plains and the Canadian Prairies) in North America.
 Their historic nomadic culture and development of equestrian culture and resistance to domination by the government and military forces of Canada and the United States have made the Plains Indian culture groups an archetype in literature and art for American Indians everywhere.
Chief Blackbird (Wash-ing-guh Sah-ba) (ca. 1750 – 1800) was the leader of the Omaha Native American Indian tribe who commanded the trade routes used by Spanish, French, British and later American traders until the late 18th century.
 He was one of the first of the Plains Indian chiefs to trade with white explorers and also believed to be the first of the Plains Indian chiefs to openly question white encroachment.
 Blackbird used trade as a means to prosperity for his people and as a way to ensure white explorers were aware that they were the guests.
 The Omaha were not warlike people, yet they were the first on the Great Plains to have mastered equestrianism around 1770 and were at one point, while Chief Blackbird was alive, the most powerful Indian tribe in the Great Plains.
The Trial of Satanta and Big Tree occurred in May 1871 in the town of Jacksboro in Jack County, Texas, United States.
 This historic trial of Native American War Chiefs of the Kiowa Indians Satanta and Big Tree for the murder of seven teamsters during a raid on Salt Creek Prairie near Jacksboro, Texas, marked the first time the United States had tried Native American Chiefs in a state court.
 The trial attracted national and international attention.
 The two Kiowa leaders, with Satank (Sitting Bear), a legendary third War Chief, were formally indicted on July 1, 1871, and tried shortly thereafter, for acts arising out of the Warren Wagon Train Raid.
Kiowa ( ) people are a Native American tribe and an indigenous people of the Great Plains.
 They migrated southward from western Montana into the Rocky Mountains in Colorado in the 17th and 18th centuries, and finally into the Southern Plains by the early 19th century.
 In 1867, the Kiowa were moved to a reservation in southwestern Oklahoma.
The Warren Wagon Train raid, also known as the Salt Creek massacre, occurred on May 18, 1871.
 Henry Warren was contracted to haul supplies to forts in the west of Texas, including Fort Richardson, Fort Griffin, and Fort Concho.
 Traveling down the Jacksboro-Belknap road heading towards Salt Creek Crossing, they encountered William Tecumseh Sherman.
 Less than an hour after encountering the famous General, they spotted a rather large group of riders ahead.
 They quickly realized that these were Native American warriors, probably Kiowa and/or Comanche.
 The corn train quickly shifted into a ring formation, and all the mules were put into the center of the ring.
 The warriors destroyed the corn supplies, killing and mutilating seven of the wagoneer's bodies.
 Five men managed to escape, one of which was Thomas Brazeale who reached Fort Richardson on foot, some 20 miles away.
 As soon as Col. Ranald S. Mackenzie learned of the incident, he informed Sherman.
 Sherman and Mackenzie searched for the warriors responsible for the raid.
 In the end, notwithstanding the intervention of Guipago (Lone Wolf), well equipped with loaded rifles and revolvers and ready to fight, 3 of the war leaders involved were arrested at Fort Sill: Satanta (White Bear), Satank (Sitting Bear), and Ado-ete (Big Tree).
 Satank attempted to escape and was killed while traveling to Fort Richardson for trial.
 The other two were tried and convicted of murder.
