Josias Wompatuck and the Titicut Reserve of the Mattakeeset - Massachusetts Tribe contradicts recent claims that the Titicut Reserve was historically "Wampanoag" territory; instead presenting the historical evidence that the Titicut Reserve was established by Josias Wompatuck in the seventeenth century to remain perpetually a possession of the Mattakeeset Massachusetts Indians. An Addendum ("Mashpee Assertions") in this second edition disputes the claims advanced in the 2012 submission by which the Mashpee Wampanoags assert claims to the Titicut Reserve.
