The Cherokee (?????, ah-ni-yv-wi-ya, in the Cherokee language) are a people native to North America, who, at the time of European contact in the sixteenth century, inhabited what is now the Eastern and Southeastern United States. Most were forcibly moved westward to the Ozark Plateau in the 1830s. They are one of the tribes referred to as the Five Civilized Tribes. According to the 2000 U.S. Census, they are the largest of the 563 federally recognized Native American tribes in the United States. [1] The Cherokee refer to themselves as Tsa-la-gi (pronounced "chaw-la-gee") or A-ni-yv-wi-ya (pronounced "ah knee yuh wee yaw", literal translation: "Principle People"). In 1654, the Powhatan were referring to this people as the Rickahockan. The word "Cherokee" may have originally been derived from the Choctaw trade language[citation needed] word "Cha-la-kee" which means "those who live in the mountains" ? or (also Choctaw) "Chi-luk-ik-bi" meaning "those who live in the cave country".[2] The Cherokee were called "Alligewi" by the Delawares. (Heckewelder) Iroquois called them Oyata?ge'ronoñ', "inhabitants of the cave country" (Hewitt).
