Final answer:
The Indian removal under the Van Buren administration involved the forced relocation of Native American tribes through the Indian Removal Act of 1830.
Step-by-step explanation:
The Indian removal under the Van Buren administration primarily involved the forced relocation of Native American tribes. It was implemented through the Indian Removal Act of 1830, which called for the voluntary removal of Native American groups living east of the Mississippi River to lands west of the river. However, in reality, tremendous pressure was applied on these groups, especially in the South, where white Americans sought to acquire lands held by the Five Civilized Tribes: the Cherokee, Creek, Choctaw, Chickasaw, and Seminole.
