Which of the following was NOT part of the original Mexican land grant to American settlers? a.
Americans received free land from Mexico.
b.
Americans took an oath of allegiance to the Mexican government.
c.
Americans were expected to become Roman Catholics.
d.
Americans were allowed to bring their slaves into Texas.

d.  Americans were allowed to bring their slaves into Texas.

Explanation:

American settlers who were allowed by the Mexican Government to settle into Texas were demanded to covert to Catholicism, to swear loyalty to the Mexican Government, and even to change their names to the respective spanish equivalent (for example Jorge for George, or Enrique for Henry). In exchange for fulfilling all these conditions, they were granted free land.

However, they were not allowed to bring their slaves with them, simply because Mexico had forbidden slavery in 1829, more than two decades earlier than the United States. Slavery was forbbiden in all of the Mexican territory, and as long mas Texas remained a part of Mexico, the settlers could not expand the slave economy that was paramount in the Deep South.
