The Indian Appropriations Act was a series of legislative measures passed by the United States Congress beginning in 1851, aimed at managing relations with Native American tribes and establishing a system for the allocation of funds for Indian affairs. These acts facilitated the creation of reservations, designed to confine Native American populations to designated areas, while also providing financial support for various services, including education and healthcare. The underlying intent was to assimilate Native Americans into American society and reduce their land ownership and sovereignty.
