How did President Lamar treat the Indians living in Texas?

President Mirabeau B. Lamar, who served as the second president of the Republic of Texas from 1838 to 1841, adopted a policy of hostility towards Native Americans. He believed in the expulsion or extermination of Indigenous tribes from Texas, viewing them as obstacles to settlement and development. Under his administration, the Texas government launched military campaigns against various tribes, particularly the Comanche and Cherokee, resulting in significant violence and displacement. This approach contrasted sharply with the more conciliatory policies of his predecessor, Sam Houston.
