Oklahoma is a state located in the south-central region of the United States. Its nickname is the "Sooner State", and is part of a region commonly known as the American "Heartland." Oklahoma City is the state's capital and largest city. The Congressional Quarterly and Census report places Oklahoma in the Southern United States.

Oklahoma became the 46th state in the Union on November 16th, 1907. The state's name comes from the Choctaw words okla meaning people and homma meaning red, literally meaning "red people"[3] and was chosen by Allen Wright, Principal Chief of the Choctaw Nation during the 1866 treaty negotiations. [4] [5] Oklahoma was almost named Sequoyah in honor of Sequoyah, the Cherokee who created the Cherokee syllabary, which gave the Cherokees a way to write and read their own language.

It is a state with a colorful history, including as a frontier state, as the destination of recently freed slaves looking for opportunity and equality, and as the heart of the oil boom in the early 20th century.

The state's early history is dominated by the Trail of Tears, the forced removal of the Five Civilized Tribes from the southeastern United States to then Indian Territory. The western and native American heritage of the state is a large part of its cultural identity; for example, Tulsa is the home to the largest, most comprehensive collection of American Western art and artifacts in the world, housed in the Gilcrease Museum.

Today, Oklahoma contains more native American tribal headquarters than any other state, as well as the nation's second largest American Indian population. [6]
