Who was to blame for the indian wars in texas

Hello, Herokee War: 1838–39 Lamar demanded that the Cherokee, who had been promised title to their land if they remained neutral during the Texas War of Independence, voluntarily relinquish their lands and all their property, and move to the Indian Territory of the United States. From this single incident, the three tribes eventually effectively united. Fehrenbach believed the union came from the necessity to protect their hunting grounds from settler incursions. First, the Kiowa and the Comanche agreed to share hunting grounds and unite in war. Hope That Helps!
