The Muscogee (Creek) Nation is a federally recognized tribe of Muscogee people, also known as the Creek, based in the U.S. state of Oklahoma.
 Calling themselves Este Mvskokvlke (] ), they are regarded as one of the historical Five Civilized Tribes of the American Southeast.
 The tribe is descended from the historic Creek Confederacy, a large, heterogeneous group of indigenous peoples of the Southeastern Woodlands.
The Chickasaw Nation is a federally recognized Native American nation, located in Oklahoma.
 They are one of the members of the Five Civilized Tribes.
 The Chickasaw Nation was created after the Chickasaw people were forcibly removed by the US federal government to Indian Territory in the 1830s.
 Their removal was part of a larger effort by the federal government to relocate Native American peoples from the eastern side of the Mississippi River; in the Southeast, these were the Cherokee, Muscogee (Creek), Seminole, Chickasaw, and Choctaw nations.
 The removals became known as the "Trail of Tears".
The term "Five Civilized Tribes" derives from the colonial and early federal period in the history of the United States.
 It refers to five Native American nations—the Cherokee, Chickasaw, Choctaw, Creek (Muscogee), and Seminole.
 These are the first five tribes that Anglo-European settlers generally considered to be "civilized" according to their own worldview, because these five tribes adopted attributes of the colonists' culture, for example, Christianity, centralized governments, literacy, market participation, written constitutions, intermarriage with white Americans, and plantation slavery practices.
 The Five Civilized Tribes tended to maintain stable political relations with the Europeans.
On the eve of the American Civil War in 1861, a significant number of Indigenous peoples of the Americas had been relocated from the Southeastern United States to Indian Territory, west of the Mississippi.
 The inhabitants of the eastern part of the Indian Territory, the Five Civilized Tribes, were suzerain nations with established tribal governments, well established cultures, and legal systems that allowed for slavery.
 Before European Contact these tribes were generally matriarchial societies, with agriculture being the primary economic pursuit.
 The bulk of the tribes lived in towns (some covering hundreds of acres and containing thousands of people) with planned streets, residential and public areas.
 The people were ruled by complex hereditary chiefdoms of varying size and complexity with high levels of military organization.
At the time of the discovery of Brazil by the Europeans, a total of 2,000 indigenous nations, divided into several thousands of tribes existed in Brazil.
 The total number of native tribes which inhabited the present day Brazil at the time of first contact is disputed, as well as difficult to ascertain.
 The names of large number of tribes who were exterminated as a result of intertribal warfare is not recorded anywhere and so is the case of several smaller tribes who were wiped out by the colonizers.
 Curt Nimuendajú gives a list of 1,400 nations in his monumental work Mapa etno-histórico do Brasil e regiões adjacentes, but he ignored many smaller (extinct) tribes in Eastern Brazil, and was unaware of some other tribes which were uncontacted at that time.
 Currently only 200 nations (790 tribes) are alive, with no survivors being reported for the remaining nations.
 However this doesn't mean all their bloodlines are extinct only their cultures.
 Brazilian Pardo and Mestizo population have mostly unknown indigenous backgrounds.
 Which can and probably have many of this indigenous peoples as ancestors.
 The Bandeirantes once hunted and enslaved indigenous peoples in the then unknown interior of Brazil from the 16th to the early 19th century.
 The indigenous peoples were eventually aculturated and integrated into European civilization.
The Muscogee, also known as the Creek and the Creek Confederacy, are a closely related group of native North American tribes or Indigenous peoples of the Southeastern Woodlands.
 Mvskoke ( ; ] ) is their autonym.
 They are originally from a single confederated native land that now comprises southern Tennessee, all of Alabama, western Georgia and part of northern Florida,
Lighthorse (or Light Horse) was the name given by the Five Civilized Tribes of the United States to their mounted police force.
 The Lighthorse were generally organized into companies and assigned to different districts.
 Perhaps the most famous were the Cherokee Lighthorsemen which had their origins in Georgia.
 Although the mounted police were disbanded when the Five Civilized Tribes lost their tribal lands in the late 19th century, some tribes still use the Lighthorse name for elements of their police forces.
Creek mythology is related to a Creek Native American tribe who are originally from the southeastern United States, also known by their original name Muscogee (or Muskogee), the name they use to identify themselves today.
 "Mvskoke" is their name in traditional spelling.
 Modern Muscogees live primarily in Oklahoma, Alabama, Georgia, and Florida.
 Their language, "Mvskoke", is a member of the Creek branch of the Muskogean language family.
 The Seminole are close kin to the Muscogee and speak a Creek language as well.
 The Creeks were considered one of the Five Civilized Tribes.
 After the Creek War many of the Creeks escaped to Florida to create the Seminole.
Native American religions are the spiritual practices of the indigenous peoples of the Americas.
 This article focuses on Native North Americans.
 Traditional Native American ceremonial ways can vary widely, and are based on the differing histories and beliefs of individual tribes, clans and bands.
 Early European explorers describe individual Native American tribes and even small bands as each having their own religious practices.
 Theology may be monotheistic, polytheistic, henotheistic, animistic, or some combination thereof.
 Traditional beliefs are usually passed down in the forms of oral histories, stories, allegories and principles, and rely on face to face teaching in one's family and community.
Indigenous Peoples' Day (also known as Native American Day) is a holiday that celebrates the Indigenous peoples of North America.
 It is celebrated in various localities in the United States.
 It began as a counter-celebration to Columbus Day, promoting Native American culture and commemorating the history of Native American peoples.
 The celebration began in Berkeley, California, through the International Indian Treaty Council, and Denver, Colorado, and now in Vermont, as a protest against Columbus Day.
 The latter is observed as a federal holiday in the United States, but it is not observed as a state holiday in every state, and most retail enterprises stay open.
 Indigenous Peoples' Day is usually held on the second Monday of October, coinciding with the federal observance of Columbus Day.
 It is similar to Native American Day, observed in September in California and Tennessee, and the same day as Indigenous Peoples' Day in South Dakota.
