USA HISTORY

Detailed explanation-1: -In 1830, Congress passed the Indian Removal Act, which authorized the U.S. to set aside lands west of the Mississippi River for tribes. Another act, passed in 1834, created what became known as Indian Territory; it included modern-day Oklahoma.

Detailed explanation-2: -These led to the relocation of nearly 50, 000 eastern Indians to the Indian Territory-what later became eastern Oklahoma. It opened up 25 million acres of eastern land to white settlement and, since the bulk of the land was in the American south, to the expansion of slavery.

Detailed explanation-3: -Under the Indian Removal Act of 1830, the Cherokee, Chickasaw, Choctaw, Creek and Seminole nations – known as the Five Tribes – were forced from their ancestral homelands in the southeast and relocated to “Indian Territory, ” as Oklahoma was then designated.

Detailed explanation-4: -In 1866 the western half of Indian Territory was ceded to the United States, which opened part of it to white settlers in 1889. This portion became the Territory of Oklahoma in 1890 and eventually encompassed all the lands ceded in 1866.

Detailed explanation-5: -Working on behalf of white settlers who wanted to grow cotton on the Indians’ land, the federal government forced them to leave their homelands and walk hundreds of miles to a specially designated “Indian Territory” across the Mississippi River.
