Law of April 6, 1830 Chapter 9.1 Mier y Teran Report (1828) ▪ In 1828, the Mexican government sent General Manuel Mier y Teran to investigate conditions in Texas. ▪ He spent almost 1 year touring Texas & wrote a report of his findings. Mier y Teran Report (1828) Mier y Teran reported the following findings: ▪ Anglo American colonists outnumbered Mexican settlers by 10 to 1. ▪ The influence of the U.S. was growing in Texas. ▪ Texas settlers ignored Mexico’s laws against slavery & trading with the U.S. Mier y Teran Report (1828) ▪ Mier y Teran concluded that Mexico must gain control of Texas before it throws “the whole nation into revolution.” Law of April 6, 1830 ▪ As a result of the Mier y Teran report, the Mexican government passed the Law of April 6, 1830 in an effort to control Texas colonists. ▪ First, this law outlawed immigration from the U.S. to Texas. Law of April 6, 1830 ▪ Secondly, this law canceled all empresario land grants that had not been fulfilled. Anglo colonization of Texas was now illegal. ▪ However, the government encouraged Mexican & European settlers to move to Texas. They would even provide land & money for these settlers. Law of April 6, 1830 Thirdly, this law stated that slaves could no longer be brought into Mexico. This would hurt Anglo Texans’ ability to develop the cotton industry. Law of April 6, 1830 ▪ Fourthly, this law placed customs duties on all goods brought into Texas from the U.S. ▪ This would hurt the Anglo Texan economy by forcing them to pay more for U.S. supplies. Tensions Over The Law ▪ Under the Mexican Constitution of 1824, the law’s provisions should have been decided by the state, not the national government. Tensions Over The Law ▪ Many Mexicans felt that the national government had gone too far. Instead of solving the problem, the Law of April 6, 1830 caused the tensions between Texas & Mexico to grow stronger.
