What are some historical myths?

21. The Texas Revolution started as a defense of the 1824 Constitution.

The more established Texians wanted to restore the constitution of Mexico, although by the time of the battle at the Alamo, there was a growing faction of secessionists. About 200 defenders of the Alamo actually left San Antonio earlier in 1835 to cross into Coahuila proper and fight with restorationist forces to depose Santa Anna. But if anything, that only increased the proportion of Anglo-Texians who wanted to join the US. Full independence was probably an unsustainable compromise.

There was a diverse mix of goals and agendas among those fighting on the Texian side. But those wanting to join Texas to the US were a substantive group that probably included Sam Houston. In older history books in Mexico they teach it was all a big plot by Tennessee Jacksonians to annex Texas (ignoring the fact that half the Tennesseeans were anti-Jackson Whigs).

Texas has a great history of outlandish plots--including one by New York abolitionists like Frederick Law Olmstead to flood the state with German immigrants in the 1850s to halt the westward expansion of slavery.
