Final answer:
Mexico allowed Anglo settlement to increase revenue from taxes but had no intention of annexing the land to America, which makes the second part of the statement false. Differences between American settlers and tejanos eventually led to the Texas Revolution.
Step-by-step explanation:
The statement that one of Mexico's reasons for allowing Anglo settlement was to gain revenue from tax money is true, as evidenced by the colonization laws that encouraged immigration for economic benefits. However, the claim that Mexico wanted to annex the land to America is false. Mexico, which had gained independence from Spain in 1821, was interested in populating the state of Coahuila y Texas. But they did not have the intention of annexing it to the United States. American settlers moved to Texas for various reasons, including the availability of land on generous terms and the opportunity to expand slavery.
Recruiting native allies did indeed play a critical role in the Spanish conquest of the Aztecs, as allies provided significant military and logistical support. The Treaty of Guadalupe Hidalgo led to Mexico's loss of a large portion of its territory to the United States, not annexation intent by Mexico itself.
Mexico's colonization laws and the resulting influx of American settlers, combined with differing attitudes and practices, particularly in regard to slavery and governance, contributed significantly to the changing relationship between Texas settlers and Mexico, eventually leading to the Texas Revolution and the subsequent annexation of Texas by the United States.
