Context paragraphs:
Major Crimes Act: The Major Crimes Act (U.S. Statutes at Large, 23:385) is a law passed by the United States Congress in 1885 as the final section of the Indian Appropriations Act of that year.  The law places certain crimes under federal jurisdiction if they are committed by a Native American in Native territory.  The law follows the 1817 General Crimes Act, which extended federal jurisdiction to crimes committed in Native territory but did not cover crimes committed by Native Americans against Native Americans.  The Major Crime Act therefore broadened federal jurisdiction in Native territory by extending it to some crimes committed by Native Americans against Native Americans.  The Major Crimes Act was passed by Congress in response to the Supreme Court of the United States's ruling in "Ex parte Crow Dog" (109 U.S. 556 (1883)) that overturned the federal court conviction of Brule Lakota sub-chief Crow Dog for the murder of principal chief Spotted Tail on the Rosebud Indian Reservation.

Shoshone: The Shoshone or Shoshoni ( or ) are a Native American tribe with four large cultural/linguistic divisions:

Native Americans in popular culture: The portrayal of Native Americans in popular culture has oscillated between the fascination with the noble savage who lives in harmony with nature, and the stereotype of the uncivilized "bad guys" in the traditional Western genre.  The common depiction of Native Americans and the relationship between the white settlers has changed significantly throughout history.  In modern times, Native Americans live completely different lives than they once did, yet retain most of their cultural beliefs and traditional practices.

Tamyen people: The Tamyen people (also spelled as "Tamien", "Thamien") are one of eight linguistic divisions of the Ohlone (Coastanoan) people groups of Native Americans who lived in Northern California.  The Tamyen lived throughout the Santa Clara Valley.  The use of the name Tamyen is on record as early as 1777, it comes from the Ohlone name for the location of the first Mission Santa Clara (Mission Santa Clara de Thamien) on the Guadalupe River.  Father Pena mentioned in a letter to Junipero Serra that the area around the mission was called "Thamien" by the native people.  The missionary fathers erected the mission on January 17, 1777 at the native village of So-co-is-u-ka.

Alcohol and Native Americans: Native Americans in the United States have historically had extreme difficulty with the use of alcohol.  Problems continue among contemporary Native Americans; 12% of the deaths among Native Americans and Alaska Natives are alcohol-related.  Use of alcohol varies by age, gender and tribe with women, and older women in particular, being least likely to be regular drinkers.  Native Americans, particularly women, are more likely to abstain entirely from alcohol than the general US population.  Frequency of use among Native Americans is generally less than the general population, but the quantity consumed when it is consumed is generally greater.

USS Luiseno (ATF-156): USS "Luiseno" (ATF-156) was an "Abnaki"-class fleet ocean tug built for the United States Navy during World War II.  Named after the Luiseño peoples (the southernmost division of the Shoshone Indians of California, who received their name from Mission San Luis Rey de Francia, the most important Spanish mission in their territory), she was the only U.S. Naval vessel to bear the name.

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.

Ionians: The Ionians ( ; Greek: Ἴωνες , "Íōnes", singular Ἴων , "Íōn") were one of the four major tribes that the Greeks considered themselves to be divided into during the ancient period; the other three being the Dorians, Aeolians, and Achaeans.  The Ionian dialect was one of the three major linguistic divisions of the Hellenic world, together with the Dorian and Aeolian dialects.

Native Americans in the American Civil War: Native Americans in the American Civil War saw Native American individuals, bands, tribes, and nations participate in numerous skirmishes and battles.  Native Americans served in both the Union and Confederate military during the American Civil War.  They were found in the Eastern, Western, and Trans-Mississippi Theaters.  At the outbreak of the war, for example, the majority of the Cherokees sided with the Union, but soon after allied with the Confederacy.  Native Americans fought knowing they might jeopardize their sovereignty, unique cultures, and ancestral lands if they ended up on the losing side of the Civil War.  28,693 Native Americans served in the Union and Confederate armies during the Civil War, participating in battles such as Pea Ridge, Second Manassas, Antietam, Spotsylvania, Cold Harbor, and in Federal assaults on Petersburg.

Novi Sad Agreement: The Novi Sad Agreement (Serbo-Croatian Latin: "Novosadski dogovor", Cyrillic: Новосадски договор) was a document composed by 25 Serbian, Croatian and Bosnian writers, linguists and intellectuals to build unity across the ethnic and linguistic divisions within Yugoslavia, and create the Serbo-Croatian language standard.
