How many acres did the nez perce have before the government took their land?

Before the U.S. government began taking their land, the Nez Perce tribe originally occupied around 7.5 million acres in the Pacific Northwest. This vast territory included parts of present-day Idaho, Oregon, and Washington. However, through a series of treaties and subsequent violations, their land was drastically reduced, culminating in the loss of nearly all their ancestral territory. By the late 19th century, the Nez Perce were confined to a much smaller reservation.
