Bullshit.
Bullshit.
Bullshit.
God, you are ignorant of Texas History.
First off, Texans didn't declare their independence until five months after the serious shooting started, and this was in 1836, a whopping fifteen years after slavery was made illegal by Mexico in 1821, and twelve years after the Constitution of 1824. There were many still hoping to stay a part of Mexico until the very end. The Declatation of Independence was only finally ratified while, in San Antonio, The Alamo was under siege. That was the last straw.
At the "highpoint" of slavery in Texas, there were still only around 5,000 slaves, tops. The bulk of these slaves working in a few large sugar, cotton and mining plantations in East Texas. There were relatively few slave owners in the bulk of Texas, and as a result, there was very little in the way of a "culture of slavery" in Texas like there was in the South when the Texas Independence Movement was formed. And this "highpoint" of Texas slavery (the slaves were mostly renamed "indentured servants" at this time, a classification the Mexican government did not challenge for the most part,) was in 1936, well after the independence movement had started, and a year after the shooting war had already started.
So, the conclusion that the repeal of slavery in Mexico caused the Texas Revolution is not only just plain false, it doesn't even match up to the timeline.
If you want to see what started the movement for independence, look to the dictatorship of Santa Anna. Santa Anna took part in several Presidential assassination plots and coup attempts in Mexico before finally coming to power in 1833. Then, after he got back from a long vacation, Santa Anna came back, tore up the liberal Mexican Constitution, declared that Mexico wasn't ready for Democracy, dissolved most of the govenment and courts, appointed himself Dictator, and, seeing Napoleon's invasion of Spain in 1808 as inspiration, started fancying himself as the "Napoleon of Mexico."
In other words, he was batshit insane with power, and he suddenly thought he was a military genius as well.
Santa Anna was no military genius though, as history would show. As he sought to centralize his power, he attempted to militarize the country in the image of his icon, Napoleon. His growing army was brutal to the citizens of Mexico and Texas.
It was the threat of being disarmed by Santa Anna's government that was the final tipping point for Texans. Thus, the battle of Gonzales in 1835.
Slavery is a blight on the otherwise proud history of Texas, no doubt. But it wasn't the cause of the revolution.
I would be remiss here in this post if I didn't mention the heroic contributions to Texas from black men like Samuel McCulloch Jr, one of the first men to be wounded in the Texas Revolution, at Goliad, Hendrick Arnold, the scout who led troops in the Battle of San Antonio, and the great Samuel G. Hardin in the Battle of San Jacinto.
Yeah. A few lied, so let's tarnish them all. Nice big broad brush you've got there, jackass.
Besides, the first slaves were brought into Texas by the Spanish. Mexico declared slavery illegal after they got their independence from Spain and mainly made slavery illegal to further punish whatever remaining Spanish were left in the country after they tried to purge them all. The Anglo Texans who took up the plantations after the Spanish were picking up the scraps of a system already in place, and the Mexican government turned a blind eye to them reclassifying them as indentured servants for well over a decade before the Texas Revolution.
Santa Anna ran for the Presidency of Mexico as a liberal...then as soon as he got back from his long siesta, declared himself Dictator. I don't see you crying about that.
