Founding of the Republic of Texas
After the victory over Mexico, Texas officially became the Republic of Texas. Now free of the Mexican government, it could set up its own laws for its own people. Seeing as many of these people were Anglo Americans who were southerners with cotton and slaves, many pushed for the continuation of slavery. On top of this, much of the new laws passed were based on the United States Constitution, and also implimented English Common law. Tejanas (Hispanic women) were effected by the success of the revolution. Under Spanish law, married women were allowed to own land and own a business. When English common law became used, Tejanas saw all their privileges vanish.1
The same can be said about black women. Under Spanish law, interracial marriages weren't uncommon. However due to the influence of Anglo Americans on the new laws, it was now next to impossible for blacks to become emancipated. Despite these oppressive laws, black women petitioned to remain in Texas and defied attempts for re-enslavement, seen, for example, in the case of Margaret Gess, who, after a lengthy and expensive legal challenge, retained her freedom1
It was also very hard for the new republic to get started. It needed help by foreign countries to be recognized as a new independent republic for trade purposes because the war had drained Texas. On top of that, the Republic of Texas was constantly battling against Native Americans as well as invasions by Mexico. Luckily for Texas, Sam Houston was a friend of then president of the United States, Andrew Jackson. Despite being an unpopular decision, Jackson officially recognized Texas as a republic in 1837.4 It was unpopular because Americans were worried about a potential annexation, as it would throw off the balance of slave and free states, something the US had tried very hard to maintain.
