“The colonies teetered at the brink of revolt in 1829, after Mexico abolished slavery. In response, President Anastasio Bustamante implemented the Laws of April 6, 1830, which, among other things, prohibited further immigration to Texas from the United States, increased taxes, and reiterated the ban on slavery. Settlers simply circumvented or ignored the laws. By 1834, an estimated 30,000 Anglos lived in Coahuila y Tejas, compared to only 7,800 Mexican-born residents.”
