What Is the "Law of April 6, 1830" in Mexico?

The law of April 6, 1830, attempted to stop immigration from the U.S. to Texas, which was owned by Mexico at the time. The law placed a tax on goods from the United States, voided settlement contracts for colonies with less than 150 residents and banned slaves from entering Texas.

The law featured provisions to encourage Mexican citizens to move into Texas by offering financial assistance, transportation to Texas and valuable land. The law also rescinded the property tax law, which had previously allowed immigrants to be exempt from paying taxes for ten years. The law of April 6, 1830, did not stop immigration from the U.S., in fact by 1834 it was estimated that there were over 30,000 Anglos compared to 7,800 Mexicans living in Texas.
