to only 7,800 Mexican-born residents. By the end of 1835, almost 5,000 enslaved Africans and African Americans lived in Texas, making up 13 percent of the non-Indian population. In 1832, Antonio López de Santa Anna led a revolt to overthrow Bustamante. Texians, or English-speaking settlers, used the rebellion as an excuse to take up arms. By mid-August, all Mexican troops had been expelled from east Texas. Buoyed by their success, Texians held two political conventions to persuade Mexican authorities to weaken the Laws of April 6, 1830. Bustamante was replaced by the liberal federalist Valentin Gomez Farias, who would attempt to reach a compromise with the Texans. In November 1833, the Mexican government attempted to address some of their concerns, repealing some sections of the law and granting the colonists further concessions, including increased representation in the state legislature. Stephen F. Austin, who had brought the first American settlers to Texas, wrote to a friend that "Every evil complained of has been remedied." Mexican authorities were quietly watchful, concerned that the colonists were maneuvering towards secession. Santa Anna overthrew Gomez Farias in April 1834, and soon revealed himself to be a centralist, inaugurating the Centralist Republic of Mexico. In 1835, the 1824 Constitution was overturned; state legislatures were dismissed, militias disbanded. Federalists throughout Mexico were appalled. Citizens in the states of Oaxaca and Zacatecas took up arms. After Santa Anna's troops subdued the rebellion in Zacatecas in May, he gave his troops two days to pillage the city; over 2,000 noncombatants were killed. The governor of Coahuila y Tejas, Agustín Viesca, refused to dissolve the legislature, instead ordering that the session reconvene in Béxar, further from the influence of the Mexican army. Although prominent Tejano Juan Seguín raised a militia company to assist the governor, the Béxar ayuntamiento (city council) ordered him not to interfere, and Viesca was arrested before he reached Texas. Public opinion in Texas was divided. Editorials in the United States began advocating complete independence for Texas. After several men staged a minor revolt against customs duties in Anahuac in June, local leaders began calling for a public meeting to determine whether a majority of settlers favored independence, a return to federalism, or the status quo. Although some leaders worried that Mexican officials would see this type of gathering as a step towards revolution, by the end of August most communities had agreed to send delegates to
