if Santa Ana had treated the Texans like free human beings instead of peasants.
He was notoreous for his cruelty with native Indian tribes and opposed Mexican independence from Spain for many years. He engaged in the whole sale slaughter of captured tribesmen or pows. He tried these tactic in Tejas and did not get the desired results. He was first and formost for himself and wanted to be on the winning side.
Texas was not the only Mexican state to rebel-but they were the only ones that won their independence.
From Wikipedia....
Several states went into open rebellion: Coahuila y Tejas, San Luis Potosí, Querétaro, Durango, Guanajuato, Michoacán, Yucatán, Jalisco, Nuevo León, Tamaulipas and Zacatecas. Several of these states formed their own governments, the Republic of the Rio Grande, the Republic of Yucatan, and the Republic of Texas. Only the Texans defeated Santa Anna and retained their independence. They and their allies from the United States declared independence from Mexico. Their fierce resistance was possibly fueled by reprisals Santa Anna committed against his defeated enemies.

Like other states discontented with the central Mexican authorities, the Texas department of the Mexican state of Coahuila y Tejas went into rebellion in late 1835 and declared itself independent on 2 March 1836. (See Texas Revolution and Republic of Texas.) Santa Anna marched north to bring Texas back under Mexican control. On March 6, 1836, at the Battle of El Alamo, Santa Anna's forces killed 187-250 Texan defenders and executed over 350 Texan prisoners at the Goliad Massacre (March 27, 1836).
Following the defeat, the Texans were reorganized under Sam Houston. Santa Anna was soon defeated by Houston's soldiers at the Battle of San Jacinto on April 21, 1836, with the Texan army shouting "Remember Goliad, Remember the Alamo!" A small band of Texan forces captured Santa Anna, dressed in a dragoon private's uniform and hiding in a marsh, the day after the battle on 22 April.
Acting Texas president David G. Burnet and Santa Anna signed the Treaties of Velasco "in his official character as chief of the Mexican nation, he acknowledged the full, entire, and perfect Independence of the Republic of Texas." In exchange, Burnet and the Texas government guaranteed Santa Anna's life and transport to Veracruz. Before Santa Anna could leave Texas, 200 angry volunteer soldiers from the United States threatened to remove him from his boat and kill him as it left the port of Velasco. Back in Mexico City, a new government declared that Santa Anna was no longer president and that the treaty with Texas was null and void.
While captive in Texas, Joel Roberts Poinsett—U.S. minister to Mexico in 1824—offered a harsh assessment of General Santa Anna's situation, stating:
Say to General Santa Anna that when I remember how ardent an advocate he was of liberty ten years ago, I have no sympathy for him now, that he has gotten what he deserves.
To this message, Santa Anna made the reply:
Say to Mr. Poinsett that it is very true that I threw up my cap for liberty with great ardor, and perfect sincerity, but very soon found the folly of it. A hundred years to come my people will not be fit for liberty. They do not know what it is, unenlightened as they are, and under the influence of a Catholic clergy, a despotism is the proper government for them, but there is no reason why it should not be a wise and virtuous one.
http://en.wikipedia.org/wiki/Antonio_L%C3%B3pez_de_Santa_AnnaPart of that bears repeating "I threw up my cap for liberty with great ardor, and perfect sincerity, but very soon found the folly of it. A hundred years to come my people will not be fit for liberty. They do not know what it is, unenlightened as they are, and under the influence of a Catholic clergy, a despotism is the proper government for them..."
And that my friends is why Texas celebrates it's Independence from Mexico, why we respect those that paid the ultimate price for their freedom both at Goliad and at the Alamo. Texas was always outnumbered by Santa Anna's army and it was the classic David vs Goliath.
