Gary Clayton Anderson, The Conquest of Texas: Ethnic Cleansing in the Promised Land, 1820-1875 (Norman: University of Oklahoma Press, 2005), 7.
I argue, however, that the situation in Texas fails to rise to the level of genocide, if genocide is defined as the intentional killing of nearly all of a racial, religious, or cultural group. I seek to draw an important distinction from it. […] Texans would have been pleased had the groups they wanted removed simply left without violence. But these groups did not. The conflict in Texas was over land; indiscriminate killing, while common during the fighting, never became a prolonged, strategic, state policy on either side. […] The ethnic conflict continued in Texas because Anglos wanted it to; ethnic cleansing, not genocide, became state policy.
