Answer the question at the end by quoting:

The Chimu culture was centered on Chimor with the capital city of Chan Chan, a large adobe city in the Moche Valley of present-day Trujillo, Peru. The culture arose about 900. The Inca emperor Topa Inca Yupanqui led a campaign which conquered the Chimu around 1470. This was just fifty years before the arrival of the Spanish in the region.
The Chimu society was a four-level hierarchical system, with a powerful elite rule over administrative centers. The hierarchy was centered at the walled cities, called ciudadelas, at Chan Chan. The political power at Chan Chan is demonstrated by the organization of labor to construct the Chimu's canals and irrigated fields. Chan Chan was the top of the Chimu hierarchy, with Farfan in the Jequetepeque Valley as a subordinate. This organization, which was quickly established during the conquest of the Jequetepeque Valley, suggests the Chimu established the hierarchy during the early stages of their expansion. The existing elite at peripheral locations, such as the Jequetepeque Valley and other centers of power, were incorporated into the Chimu government on lower levels of the hierarchy. These lower-order centers managed land, water, and labor, while the higher-order centers either moved the resources to Chan Chan or carried out other administrative decisions. Rural sites were used as engineering headquarters, while the canals were being built; later they operated as maintenance sites. The numerous broken bowls found at Quebrada del Oso support this theory, as the bowls were probably used to feed the large workforce that built and maintained that section of canal. The workers were probably fed and housed at state expense. The state governed such social classes until the empire of the Sican culture conquered the kingdom of Lambayeque, Peru. The legends of war were said to have been told by the leaders Naylamp in the Sican language and Tacayanamo in Chimu. The people paid tribute to the rulers with products or labor. By 1470, the Inca Empire from Cusco defeated the Chimu. They moved Minchancaman, the final Chimu emperor, to Cusco and redirected gold and silver there to adorn the Qurikancha.

who was at the bottom of the hierarchy?

lower-order centers managed land, water, and labor, while the higher-order centers either moved the resources to Chan Chan or carried out other administrative decisions.

Burton was born to American parents at the U.S. Army Landstuhl Regional Medical Center in West Germany. His mother, Erma Gene (nee Christian), was a social worker, administrator, and educator. His father, Levardis Robert Martyn Burton, was a photographer for the U.S. Army Signal Corps at the time he was stationed at Landstuhl. Burton and his two sisters were raised by his mother in Sacramento, California.
Burton first appeared on television in a drama about a misunderstood deaf boy. LeVar Burton made his film acting debut in 1977 when he played Kunta Kinte in the ABC award-winning drama series Roots, based on the novel by Alex Haley. Burton's audition for the role of Kinte was the first of his professional career. As a result of his performance, he was nominated for the Emmy for Best Actor in a Drama Series. Burton reprised the role of Kunta Kinte in the 1988 television film Roots: The Gift. When asked about the societal impacts of Roots, Burton is quoted as saying, "It expanded the consciousness of people. Blacks and whites began to see each other as human beings, not as stereotypes. And if you throw a pebble into the pond, you're going to get ripples. I think the only constant is change, and it's always slow. Anything that happens overnight is lacking in foundation. Roots is part of a changing trend, and it's still being played out." Burton played a role as a visitor to Fantasy Island, was a participant in Battle of the Network Stars, a guest of the Muppet Show's televised premiere party for the release of The Muppet Movie, and a frequent guest on several game shows. In 1986, he appeared in the music video for the song "Word Up!" by the funk/R&B group Cameo. Burton accepted an invitation to host Rebop, a multicultural series designed for young people ages 9-15, produced by WGBH for PBS.
