"To those pioneer Indians whose courage and fortitude, perseverance and achievement sustained them through travail and disaster and earned for them the name of The Five Civilized Tribes, and who laid the foundation for the State of Oklahoma." - These words by Grant Foreman were printed at the beginning of a letter postmarked April 15, 1966, which was sent out in preparation for the opening of the Five Civilized Tribes Museum.
