Final answer:
Yellowstone National Park was created in 1872 after forcibly removing at least six Native American groups. This was part of broader US policies that included the Indian Removal Act of 1830, leading to displacement and suffering for numerous tribes.
Step-by-step explanation:
The national park created in 1872 where at least six Native American groups were forcibly removed is Yellowstone National Park. The creation of the park followed a history of forced relocations of Native Americans, often to reservations far from their ancestral lands. The Indian Removal Act of 1830 led to the displacement of tens of thousands of Native Americans, including the infamous Trail of Tears, where many perished during forced marches to what is now Oklahoma. This act affected Southern tribes, while in the North, others like the Sauk, Shawnee, and Ottawa were moved to Indian Territory following agreements. These actions had a lasting impact on the Native American communities, resulting in significant loss of life, land, and cultural fragmentation.
