In 1830, as a result of the Treaty of Dancing Rabbit Creek ,the Choctaw were forcibly relocated from their homelands in the Mississippi Valley to what later became known as Oklahoma. Twenty thousand Choctaw began the journey. Approximately seven thousand survived. This was the infamous "Trail of Tears".
The Choctaws were recognized as the first to use their native language as unbreakable code in World War I. The Choctaw language was used in World War II once more. Choctaws conversed in their language over field radios to coordinate military positions, giving exact details and locations without fear of German interception.
