However, the terminology is used throughout other periods to characterize the two groups and is used in various texts. With that said, those who developed commercial operations soon became intensive agriculturalists, cultivated large tracts of land and became wealthy plantation holders. They cultivated cotton, wheat and barley and adopted the culture of the southern aristocracy, which included slave ownership (Graebner, 1945). Some Cherokees who engaged in subsistence activities farmed communally, but it was becoming less common. From 1800 to 1820 the Cherokees adopted many additional innovations such as the Euro-American education system, literacy and Christianity. U.S.'s republican form of government was also adopted as the political structure of Cherokee Nation (Wahrhaftig, 1978). Further, Malone cited by Goodwin (1977) states "by the 1830's, the Cherokees had become a nation of farmers, with 2,700 families, or 93% of the population, managing their own farms and tending to thousands of cattle, swine, horses" (p. 140). In 1819, Congress created the Civilization Fund which aimed to civilize Indians through farming. Numerous schools run by Christian churches began to offer education to Indian males and females to help them learn tasks to integrate them into society. Males were taught to farm and maintain livestock while women were taught to weave, spin and cook (Hurt, 1987). Tensions over land increased between American settlers and Cherokees.

Jefferson hoped to reduce Indian land holdings, which would allow more land to become available for white settlers. He also hoped that eventually the Indians would move west. Hurt cites Esarey "To promote this disposition to exchange lands which they have to spare and we
