He was active in promoting trade and currying the good favor of the Mexican authorities, aiding them in the suppression of the Fredonian Rebellion of Haden Edwards. Some historians consider the Fredonian Rebellion to be the beginning of the Texas Revolution. Although "premature ...  the Fredonian Rebellion sparked the powder for later success." For this event, Austin raised troops to fight with Mexican troops against the Texas rebels. With the colonists numbering more than 11,000 by 1832, they were becoming less amenable to Austin's cautious leadership, and also, the Mexican government was becoming less cooperative. It was concerned with the growth of the colony and the efforts of the U.S. government to buy the state from them. The Mexican government had attempted to stop further U.S. immigration as early as April 1830, but Austin's skills gained an exemption for his colonies. He granted land to immigrants based on to the husband, 320 to the wife, 160 for every child, and 80 for every slave.
