Why did fighting break out between American Indians and the US Army in the Black Hills region? Select all that apply.

Gold was discovered in the Black Hills, which the Sioux considered their land, drawing miners and settlers into the region. Their pressure for access to more land, along with the government’s efforts to force American Indians onto reservations, increased conflict and led to fighting. The government did not consistently protect Sioux lands or halt settlement, so D is not a reason.
