Indigenous languages of Arizona: Arizona, a state in the southwestern region of the United States of America, is known for its high population of Native Americans.  Arizona has the third highest number (and the sixth highest percentage) of Native Americans of any state in the Union (See Demographics of Arizona).  Out of the entire US population of 2.9 million Native Americans, roughly 286,680 live in Arizona, representing 10% of the country's total Native American population.  Only California and Oklahoma have more Native Americans than Arizona by number.  Arizona also has the highest proportion of land allocated to Native American reservations, at 28%.  Arizona has five of the twelve largest Indian reservations in the United States, including the largest, the Navajo Nation, and the third-largest, the Tohono O'odham Nation.  Also, Arizona has the largest number of Native American language speakers in the United States.

The house was built in 1837 on lands that had once belonged to the Creek Confederacy.  Wellborn had been wounded in a battle during the Creek War of 1836, and died of the wound in 1841.  His family continued to live at the residence.

Consortium for Graduate Study in Management: The Consortium for Graduate Study in Management was founded in 1966 and is a 501(c)(3) organization dedicated to ensuring the equal representation of African Americans, Hispanic Americans and Native Americans in management careers in the business community of the United States of America.  The Consortium is so named for the collaboration among its staff and board of trustees; its 19 member MBA programs; and its approximately 75 corporate partners, which work together toward the mission "to enhance diversity in business education and leadership by helping to reduce the serious underrepresentation of African Americans, Hispanic Americans and Native Americans in both our member schools’ enrollments and the ranks of management."

List of Indian massacres: In the history of the European colonization of North America, an atrocity termed "Indian massacre" is a specific incident wherein a group of people (military, mob or other) deliberately kill a significant number of relatively defenseless or innocent people—usually civilian noncombatants or to the summary execution of prisoners-of-war.  The term refers to the killings of Euro-Americans by Native Americans (Indians) as well as to killings of Native Americans by Euro-Americans and/or by other Native Americans.

Daybreak Star Cultural Center: The Daybreak Star Cultural Center is a Native American cultural center in Seattle, Washington, described by its parent organization United Indians of All Tribes as "an urban base for Native Americans in the Seattle area."  Located on 20 acres (81,000 m²) in Seattle's Discovery Park in the Magnolia neighborhood, the center developed from activism by Bernie Whitebear and other Native Americans, who staged a generally successful self-styled "invasion" and occupation of the land in 1970.  Most of the former Fort Lawton military base had been declared surplus by the U.S. Department of Defense.  "The claim [Whitebear and others made] to Fort Lawton was based on rights under 1865 U.S.-Indian treaties promising reversion of surplus military lands to their original owners."

Alabama people: The Alabama or Alibamu ("Albaamaha" in the Alabama language) are a Southeastern culture people of Native Americans, originally from Alabama.  They were members of the Muscogee Creek Confederacy, a loose trade and military organization of autonomous towns; their home lands were on the upper Alabama River.

Koasati language: Koasati (also Coushatta) is a Native American language of Muskogean origin.  The language is spoken by the Coushatta people, most of whom live in Allen Parish north of the town of Elton, Louisiana, though a smaller number share a reservation near Livingston, Texas, with the Alabama people.  In 1991, linguist Geoffrey Kimball estimated the number of speakers of the language at around 400 people, of whom approximately 350 live in Louisiana.  The exact number of current speakers is unclear, but Coushatta Tribe officials claim that most tribe members over 20 speak Koasati.  In 2007, the Coushatta Tribe of Louisiana, in collaboration with McNeese State University and the College of William and Mary, began the Koasati (Coushatta) Language Project as a part of broader language revitalization efforts with National Science Foundation grant money under the Documenting Endangered Languages program.

American Indian Wars: The American Indian Wars, Canadian Indian Wars or Indian Wars, were the multiple armed conflicts of European governments and colonists, and later American and Canadian settlers or the American and Canadian governments, against the native peoples of North America.  These conflicts occurred in the current boundaries of the United States and Canada from the time of earliest colonial settlements until 1924.  In many cases, wars resulted from competition for resources and land ownership as Europeans and later Americans and Canadians encroached onto territory which had been traditionally inhabited by Native Americans.  Warfare and raiding also took place as a result of conflicts between European governments and later the United States and Canada.  These governments enlisted Native Americans tribes to help them conduct warfare against each other's settlements and their Native American allies.

List of counties in Alabama: The U.S. state of Alabama has 67 counties.  Each county serves as the local level of government within its borders.  The land enclosed by the present state borders was joined to the United States of America gradually.  Following the American Revolutionary War, West Florida was ceded to Spain by treaty while the remainder was organized primarily as the Mississippi Territory, and later the Alabama Territory.  The territorial assembly established some of the earliest county divisions that have survived to the present, including the earliest county formation, that of Washington County, created on June 4, 1800.  In 1814, the Treaty of Fort Jackson opened the territory to American settlers, which in turn led to a more rapid rate of county creation.  Alabama was admitted to the Union as the 22nd state in 1819.  The Alabama state legislature formed additional counties from former native lands as the Indian Removal Act took effect and settlers populated different areas of Alabama.  In 1820, Alabama had 29 counties.  By 1830 there were 36 and Native Americans still occupied large areas of land in northeast and far western Alabama.  By 1840, 49 counties had been created; 52 by 1850; 65 by 1870; and the present 67 counties by 1903.  Houston County was the last county created in the state, on February 9, 1903.
