Final answer:
False. Stephen Austin was not the only empresario in Texas. Moses Austin, Green DeWitt, and Martín de León were other important empresarios who brought settlers to Texas.
Step-by-step explanation:
False. Stephen Austin was not the only empresario in Texas. An empresario was someone who brought settlers to the region in exchange for land grants. While Stephen Austin was indeed an important empresario, there were others as well.
For example, Moses Austin, Stephen Austin's father, was the first empresario in Texas. He requested permission to settle 300 American residents in Texas and Spain agreed on the condition that the settlers convert to Roman Catholicism. Other empresarios, such as Green DeWitt and Martín de León, also played significant roles in bringing settlers to Texas.
Therefore, it is false to say that Stephen Austin was the only empresario in Texas.
