Biloxi was a Siouan language spoken in what is now Mississippi.
The Biloxi tribe was decimated by a smallpox epidemic, and the survivors migrated westward and merged with
the Tunica Indians, with whom they share a Louisiana reservation today.
Though the Tunica and Biloxi Indians were friends and allies, their languages were entirely unrelated, and since they were
unable to communicate effectively in their native languages, both tribes shifted to French. The Biloxi language has not been spoken in
more than a century.
