Final answer:
Southeast tribes had diverse obligations to Europeans, including land transfers, possible religious conversions, and other facets of forced assimilation, with many tribes later fighting for their treaty rights.
Step-by-step explanation:
The obligations that Southeast tribes had towards Europeans were diverse and multifaceted. Primarily, Europeans were in North America for economic gain from natural resources and the expansion of their territories. Tribes faced the transfer of tribal lands, forced assimilation, and sometimes conversion to European religions. Furthermore, European colonization led to the decimation of indigenous populations through warfare and diseases.
Beyond these losses, the United States government frequently failed to honor treaty obligations, compelling various tribes to fight for their rights over extended periods. It is important to note that these experiences varied among tribes, with some seeking legal redress for the government's failure to uphold treaties and others striving for federal recognition to establish trust relationships.
