the political economy of race had different consequences for the descendants of aboriginal americans and african slaves. the 19th-century blood quantum rule meant that it was relatively easier for a person of mixed euro-amerindian ancestry to be accepted as white. the offspring of a few generations of intermarriage between amerindians and whites likely would not have been considered amerindian (at least not in a legal sense). amerindians could have treaty rights to land, but because an individual with only one amerindian great-grandparent no longer was classified as amerindian, he lost a legal claim to amerindian land, under the allotment rules of the day. according to sider's theory, whites were more easily able to acquire amerindian lands. on the other hand, the same individual who could be denied legal standing in a tribe, according to the government, because he was "too white" to claim property rights, might still have enough visually identifiable amerindian ancestry to be considered socially as a "half-breed" or breed, and stigmatized by both communities.
