USA HISTORY

Detailed explanation-1: -Diseases brought by Spanish missionaries killed many American Indians. American Indians were moved to the coast to make room for the missionaries. Fighting broke out among American Indians over trade with the missionaries. American Indians starved because buffalo were wiped out by the missionaries.

Detailed explanation-2: -The high rates of death inevitably destroyed tribal communities and tribal culture. The Mexican Secularization Act of 1833 granted only a few mission Indians land, but the vast majority of natives fled the missions and became an exploited laboring class on Spanish and Mexican ranchos across the State.

Detailed explanation-3: -Despite being affected before the introduction of missions, the buildings allowed rodents to infiltrate living areas and spread disease more rapidly. Some of the most common diseases were typhus, measles and smallpox. Many natives were living in cramped spaces with poor hygiene and poor nutrition.

Detailed explanation-4: -The story of the mission system in Texas was one of both successes and failures. It was a failure in that it failed to bring most of the Indians of Texas into the orbit of New Spain on a permanent basis.

Detailed explanation-5: -Thus, the difficult geography, the weak missions, and hostile Indians were the main causes of the near failure of the Spanish colonies in Texas.
