What did William McIntosh do by signing the Treaties of Indian Springs?

By signing the Treaties of Indian Springs in 1825, William McIntosh, who was a Creek Indian chief, ceded a significant portion of Creek lands in present-day Alabama and Georgia to the United States government. The treaties resulted in the removal of several thousand Creek Indians from their ancestral lands, opening up the territory for white settlement. Many Creek Indians, however, were outraged by McIntosh's actions, as they believed he had no authority to make such agreements. Ultimately, McIntosh's signing of the treaties played a significant role in the Creek Indian War of 1836, which culminated in the forced removal of Creek Indians to Indian Territory (present-day Oklahoma).
