Why did mexico want to stop americans from settling in texas after 1824?

Tejas, in English history books usually referred to as Mexican Texas, was a province of Mexico between 1821 and 1836. Mexico gained independence from Spain in 1821 in its war of independence. Initially, Mexican Texas operated very similarly to Spanish Texas. However, the 1824 Constitution of Mexico set up a federal structure, with Tejas joined with the province of Coahuila to form the state of Coahuila y Tejas.

Tejas was grossly underpopulated, with about 3500 settlers living in the whole of Tejas in 1821, mostly congregated at San Antonio and La Bahia,[1] despite efforts by the authorities to increase the settler population along the frontier. The settler population was overwhelmingly outnumbered by the indigenous tribes. To increase settler numbers, Mexico enacted the General Colonization Law in 1824, which enabled all heads of household, regardless of race, religion or immigrant status, to land in Mexico. The first empresarial grant had been made under Spanish control to Stephen F. Austin, whose settlers, known as the Old Three Hundred, settled along the Brazos River in 1822. The grant was later ratified by the Mexican government. Twenty-three other empresarios brought settlers to the state, the majority from the United States of America, while others came from Mexico and Europe.

After concerns over attitudes of US citizens in Tejas, the Law of April 6, 1830 outlawed further immigration of US citizens to Texas. Several new presidios were established in the region to monitor immigration and customs practices. Angry colonists held a convention in 1832 to demand that US citizens be allowed to immigrate. A convention the following year proposed that Texas become a separate Mexican state. Although Mexico implemented several measures to appease the colonists, Antonio Lopez de Santa Anna's measures to transform Mexico from a federalist to a centralist state motivated the Texan colonists to revolt.

unbeknownst to the slave-ship captains, the daily dancing and exercise regime and vernacular dance are also derived from america's african-based slave legacy. both are african-american cuisines from the slavery era.

explanation:

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
