Problem: Background: Thelonious Sphere Monk was born two years after his sister Marion on October 10, 1917, in Rocky Mount, North Carolina, and was the son of Thelonious and Barbara Monk. His badly written birth certificate misspelled his first name as "Thelious" or "Thelius." It also did not list his middle name, taken from his maternal grandfather, Sphere Batts. A brother, Thomas, was born in January 1920.
Context: In his early teens, Monk toured with an evangelist, playing the church organ, and in his late teens he began to find work playing jazz. In the early to mid-1940s, he was the house pianist at Minton's Playhouse, a Manhattan nightclub. Much of Monk's style was developed during his time at Minton's, when he participated in after-hours cutting contests, which featured many leading jazz soloists of the time. Monk's musical work at Minton's was crucial in the formulation of bebop, which would be furthered along by other artists, including Dizzy Gillespie, Charlie Christian, Kenny Clarke, Charlie Parker, and, later, Miles Davis. Monk is believed to be the pianist featured on recordings Jerry Newman made around 1941 at the club. Monk's style at this time was later described as "hard-swinging," with the addition of runs in the style of Art Tatum. Monk's stated influences included Duke Ellington, James P. Johnson, and other early stride pianists. In the documentary Thelonious Monk: Straight, No Chaser, it is stated that Monk lived in the same neighborhood in New York City as Johnson and knew him as a teenager. Mary Lou Williams, who mentored Monk and his contemporaries, spoke of Monk's rich inventiveness in this period, and how such invention was vital for musicians, since at the time it was common for fellow musicians to incorporate overheard musical ideas into their own works without giving due credit. "So, the boppers worked out a music that was hard to steal. I'll say this for the 'leeches,' though: they tried. I've seen them in Minton's busily writing on their shirt cuffs or scribbling on the tablecloth. And even our own guys, I'm afraid, did not give Monk the credit he had coming. Why, they even stole his idea of the beret and bop glasses." In 1944 Monk made his first studio recordings with the Coleman Hawkins Quartet. Hawkins was one of the earliest established jazz musicians to promote Monk, and the pianist later returned the favor by inviting Hawkins to join him on a 1957 session with John Coltrane.

Problem: Background: Native Americans, also known as American Indians, Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States. There are over 500 federally recognized tribes within the U.S., about half of which are associated with Indian reservations. The term excludes Native Hawaiians and some Alaska Natives. The ancestors of modern Native Americans arrived in what is now the United States at least 15,000 years ago, possibly much earlier, from Asia via Beringia.
Context: Iroquois Culture: The Iroquois League of Nations or "People of the Long House", based in present-day upstate and western New York, had a confederacy model from the mid-15th century. It has been suggested that their culture contributed to political thinking during the development of the later United States government. Their system of affiliation was a kind of federation, different from the strong, centralized European monarchies.Leadership was restricted to a group of 50 sachem chiefs, each representing one clan within a tribe. The Oneida and Mohawk people had nine seats each; the Onondagas held fourteen; the Cayuga had ten seats; and the Seneca had eight. Representation was not based on population numbers, as the Seneca tribe greatly outnumbered the others. When a sachem chief died, his successor was chosen by the senior woman of his tribe in consultation with other female members of the clan; property and hereditary leadership were passed matrilineally. Decisions were not made through voting but through consensus decision making, with each sachem chief holding theoretical veto power. The Onondaga were the "firekeepers", responsible for raising topics to be discussed. They occupied one side of a three-sided fire (the Mohawk and Seneca sat on one side of the fire, the Oneida and Cayuga sat on the third side.) Elizabeth Tooker, an anthropologist, has said that it was unlikely the US founding fathers were inspired by the confederacy, as it bears little resemblance to the system of governance adopted in the United States. For example, it is based on inherited rather than elected leadership, selected by female members of the tribes, consensus decision-making regardless of population size of the tribes, and a single group capable of bringing matters before the legislative body. Long-distance trading did not prevent warfare and displacement among the indigenous peoples, and their oral histories tell of numerous migrations to the historic territories where Europeans encountered them. The Iroquois invaded and attacked tribes in the Ohio River area of present-day Kentucky and claimed the hunting grounds. Historians have placed these events as occurring as early as the 13th century, or in the 17th century Beaver Wars. Through warfare, the Iroquois drove several tribes to migrate west to what became known as their historically traditional lands west of the Mississippi River. Tribes originating in the Ohio Valley who moved west included the Osage, Kaw, Ponca and Omaha people. By the mid-17th century, they had resettled in their historical lands in present-day Kansas, Nebraska, Arkansas and Oklahoma. The Osage warred with Caddo-speaking Native Americans, displacing them in turn by the mid-18th century and dominating their new historical territories.
