The process of assimilation generally had a negative impact on Native American communities, and oftentimes assimilation was not successful and was strongly resisted by the tribes.

Another aspect of assimilation that had a negative impact was the US attempt to incorporate Native Americans and their land into the greater country by offering citizenship and land allotments, forcing a political and social model on them that was inconsistent with their long-established traditions and culture.
