There is a tradition that when the Creek people incorporated tribes of other nations into their confederacy, these tribes never kept up their own customs and peculiarities for any length of time, but were subdued in such a manner as to conform with the dominant race. As a confirmation of this, it is asserted that the Creeks annihilated the Yámassi Indians completely, so that they disappeared entirely among their number; that the Tukabatchi, Taskígi and other tribes of foreign descent abandoned their paternal language to adopt that of the dominant Creeks.
