What was the purpose of the law enacted on April 6, 1830, in Mexico?

The law enacted on April 6, 1830, in Mexico aimed specifically to regulate and ensure that empresarios adhered to the existing colonization laws. This legislation was a response to concerns about the influx of U.S. settlers in Texas and aimed to reinforce the Mexican government's control over the region. By ensuring compliance with colonization laws, the law was intended to stabilize the situation in Texas and mitigate any potential for unrest or rebellion, which was heightened by the growing number of American immigrants who often disregarded local regulations.

The focus was on maintaining order and ensuring that immigrants and settlers adhered to Mexican policies, including commitments to convert to Catholicism and speak Spanish. Thus, the correct answer highlights the law's role in enforcing compliance rather than promoting immigration, granting land, or establishing military presence, which were not the primary motivations of this particular legislation.
