Final answer:
History records verify that early Spanish missions, including those in East Texas, faced challenges such as disease that could lead to failure. It is true that the Spanish military and religious motives were closely linked during their reconquest of the Iberian Peninsula. Recruiting native allies was also a true and significant strategy in the Spanish conquest of the Aztec.
Step-by-step explanation:
The question regarding the first Spanish mission in East Texas being ravished by disease and ending in failure investigates a historical event. Upon review of historical records, it is indeed true that early Spanish missions often faced significant challenges including diseases, which led to failures. However, specific detail about the 'first' mission in East Texas is not provided, as the success or failure of early missions can vary based on the particular mission being referred to and documented evidence.
In the context of the Spanish impact in the Americas, it is true that militaristic and religious aspects were intertwined in their acts of conquest, such as the reconquering of the Iberian Peninsula. Moreover, aligning with the tactics used by the Spanish, recruiting native allies was critical for their success during the conquest of the Aztec Empire.
Additionally, the Treaty of Guadalupe Hidalgo indeed led to Mexico losing a substantial portion of its land, which marks a significant event in North American history. This context on the Spanish missions and conquests provides a broader understanding of the struggles and outcomes of their colonial activities.
