Probably this is as much as could have realistically been taken.
Mexico didn't have the American style plantation slavery, but there was a thriving underground trade in house slaves (servant types)... apparently, there was a demand for Native American children, who were kidnapped from their villages, and raised to be 'exotic' domestic servants.Without going into the comparison between chattel slavery and peonage, slavery has been outlawed in Mexico since 1811 and the Mexicans are proud and happy about that.
Good Lord, that is so wrong. The reasons behind the Texan WoI were strikingly similar to the ARW: the American colonists had been managing their own affairs for a long time, and Mexico suddenly was going to lower the boom on them, taking away all of their special tax and customs waivers, stopping completely any further American immigration, and generally keeping a firmer grip on the place. The Americans protested, and Santa Anna practically guaranteed a rebellion by putting Stephen Austin into a jail and ruining his health. Santa Anna did make a lot of noise about freeing the slaves during his campaign in TX, but he freed very few of them...Mexico abolished slavery in 1829, and as much as Texans hate to admit it, it was their insistence on practicing slavery that lead to the Texas War of Independence.
