Answer:
Spanish period
Step-by-step explanation:
The variety of the peoples and cultures whom Europeans first found in Texas and the different histories of each group make generalizations about Indians hazardous. Texas was not simply a Spanish-Indian or Anglo-Indian frontier, but rather a multi-sided frontier, a Spanish-Anglo-Comanche-Wichita-Apache-etc. frontier, where multiple groups acted for their own reasons. A few generalizations, however, apply to all Texas Indian groups. First, diseases introduced by the Europeans decimated them, especially after mission and military institutions brought people in contact so that they could be infected (see HEALTH AND MEDICINE). More broadly, anthropologist John C. Ewers has identified no fewer than thirty major epidemics -mainly of smallpox and cholera-between 1528 and 1890 that wiped out perhaps 95 percent of Texas Indians.
