What is "chalahgawtha"

Chalahgawtha (or, more commonly in English, Chillicothe) was the name of one of the five divisions (or bands) of the Shawnee, a Native American people, during the 18th century, as well as the name of the principal village of the division. The other four divisions were the Mekoche, Kispoko, Pekowi, and Hathawekela. (All five division names have been spelled in a great variety of ways.) Together these divisions formed the loose confederacy that was the Shawnee tribe.
