' A war of extermination is raging in Texas—a war of barbarism and of despotic principles, waged by the mongrel Spanish-Indian and Negro race, against civilization and the Anglo-American race.
For fifteen years I have been laboring like a slave to Americanize Texas—to form a nucleus around which my native countrymen could collect and grow into a solid body that would forever be a barrier of safety to the southwestern frontier.'

— Stephen F. Austin, 1836

' As surely as to-morrow’s sun will rise and pursue its bright course along the firmament of heaven, so certain, it appears to my mind, must the Anglo-Saxon race pervade the whole southern extremity of this vast continent, and the people whom God has placed here in this land, spread, prevail, and pervade throughout the whole rich empire of this great hemisphere ... there is an instinct in the American people which impels them onward, which will lead them to pervade this continent. ... as their birth-right. '

— Sam Houston, 1848
