The term "Indian Territory" refers to a region in the central United States that was designated for the relocation of Native American tribes during the 19th century. This area, primarily located in what is now Oklahoma, was established by various treaties and acts, including the Indian Removal Act of 1830. It served as a refuge for tribes such as the Cherokee, Choctaw, and Creek. In 1907, Indian Territory was merged with Oklahoma Territory to form the state of Oklahoma. The region's history is marked by the forced removal of Native Americans from their ancestral lands, leading to significant cultural and social changes for the tribes involved. Today, it is recognized for its rich Native American heritage.
