A 50,000-year-old indigenous Native American tribe that has weathered the conquistadors, numerous wars with the Europeans, the American Revolution and the Civil War is now fighting to preserve its language and culture by embracing modern technology.

There are 6,000 languages spoken in the world but linguists fear that 50% of them will become extinct within the next century. In the U.S., 175 Native American languages are spoken, but fewer than 20 are expected to survive the next 100 years.

The language of the Chickasaws, known as "Chikashshanompa", is a 3,000-year-old living language that is categorized by Unesco as being "severely endangered"...
