Problem: Marian Anderson (February 27, 1897 - April 8, 1993) was an African-American contralto and one of the most celebrated singers of the twentieth century. Music critic Alan Blyth said: "Her voice was a rich, vibrant contralto of intrinsic beauty." Most of her singing career was spent performing in concert and recital in major music venues and with famous orchestras throughout the United States and Europe between 1925 and 1965. Although offered roles with many important European opera companies, Anderson declined, as she had no training in acting.

In 1933, Anderson made her European debut in a concert at Wigmore Hall in London, where she was received enthusiastically. She spent the early 1930s touring throughout Europe where she did not encounter the racial prejudices she had experienced in America. In the summer of 1930, she went to Scandinavia, where she met the Finnish pianist Kosti Vehanen who became her regular accompanist and her vocal coach for many years. She also met Jean Sibelius through Vehanen after he had heard her in a concert in Helsinki. Moved by her performance, Sibelius invited them to his home and asked his wife to bring champagne in place of the traditional coffee. Sibelius commented to Anderson of her performance that he felt that she had been able to penetrate the Nordic soul. The two struck up an immediate friendship, which further blossomed into a professional partnership, and for many years Sibelius altered and composed songs for Anderson to perform. He created a new arrangement of the song "Solitude" and dedicated it to Anderson in 1939. Originally The Jewish Girl's Song from his 1906 incidental music to Belshazzar's Feast, it later became the "Solitude" section of the orchestral suite derived from the incidental music. In 1934, impresario Sol Hurok offered Anderson a better contract than she previously had with Arthur Judson. He became her manager for the rest of her performing career and through his persuasion she came back to perform in America. In 1935, Anderson made her first recital appearance in New York at Town Hall, which received highly favorable reviews by music critics. She spent the next four years touring throughout the United States and Europe. She was offered opera roles by several European houses but, due to her lack of acting experience, Anderson declined all of those offers. She did, however, record a number of opera arias in the studio, which became bestsellers. Anderson, accompanied by Vehanen, continued to tour throughout Europe during the mid-1930s. She visited Eastern European capitals and Russia and returned again to Scandinavia, where "Marian fever" had spread to small towns and villages where she had thousands of fans. She quickly became a favorite of many conductors and composers of major European orchestras. During a 1935 tour in Salzburg, the conductor Arturo Toscanini told her she had a voice "heard once in a hundred years". In the late 1930s, Anderson gave about 70 recitals a year in the United States. Although by then quite famous, her stature did not completely end the prejudice she confronted as a young black singer touring the United States. She was still denied rooms in certain American hotels and was not allowed to eat in certain American restaurants. Because of this discrimination, Albert Einstein, a champion of racial tolerance, hosted Anderson on many occasions, the first being in 1937 when she was denied a hotel before performing at Princeton University. She last stayed with him months before he died in 1955.

Question:
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.
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.
