What caused Texas to become an independent republic?

Answer 1

In 1836 the Texas government asked Congress to annex Texas to the union. Before that they were an independent nation because they won the war with Mexico and signed to Treaty of Guadalupe Hidalgo.

Mexico had broken free from Spain, and adopted the Constitution of 1824. After its war with Spain, the Mexican economy was extremely weak. The government encouraged Immigration in to Texas (which was part of Mexico at the time). Many Americans began moving in to Texas, and soon there were far more American immigrants in Texas than there were Mexicans. In response to this, the Mexican government banned further American immigration in to Texas, and got rid of some of the laws that had helped American immigrants. The American immigrants ignored these new anti-immigrant laws. As the number of Americans moving in to Texas increased, so did Texan resentment of the Mexican government. The Mexican constitution gave citizens less rights than the American one (there was no separation of church and state, for example. Catholicism was the national religion). The Mexican government, meanwhile, was fearing that Texas might rebel, so they arrested some Texan farmers and dismantled Texan militias. This made Texans angry, and they eventually declared themselves independent.

I hope this helped! :)
