Answer:
In 1826, American anglos who had settled in Mexican Texas were required by law to become Mexican citizens, speak Spanish, follow the Catholic religion and abide by Mexican laws. However, many American anglos in Texas ignored or openly defied these laws. Some engaged in illegal slave trafficking, while others continued to speak English instead of learning Spanish. Some also refused to convert to Catholicism and ignored Mexican laws they disagreed with. These actions contributed to rising tensions between the Anglo-American settlers and the Mexican government, eventually leading to the Texas War of Independence in 1835-36.
