What was Stephen F. Austin trying to tell the leaders of Mexico about Texans?

Stephen Fuller Austin was a reluctant revolutionary. His father, Moses Austin, won permission from the Mexican government in 1821 to settle 300 Anglo-American families in Texas. When Moses died before realizing his plans, Stephen took over and established the fledgling Texas community on the lower reaches of the Colorado and Brazos Rivers. Periodic upheavals in the government of the young Mexican Republic forced Austin to constantly return to Mexico City where he argued for the rights of the American colonists in Texas, representing their interests as a colonial founder. Yet, Austin remained confident that an Anglo-American state could succeed within the boundaries of the Mexican nation.
