And slavery, notably absent from the constitution of 1824, played no part? I think the texans desire to join with the US if independence wasn't viable must have also played a part as well, no?
Edit: Are u also implying that the white settlers were not cultural distinct from Mexicans? That's a pretty big part of my culture bomb analogy.
Slavery was outlawed by the Constitution of 1824, but the settlers worked around it by converting their slaves into perpetual indentured servants. They knew what they were getting into when they went to Tejas.
They were different from the Mexicans culturally, but is America the only country allowed to take on different ethnic groups without being "culture bombed"? Mexico had been home to all sorts of ethnic groups, social stratification, political ideologies, etc.
The white settlers struck out on their own due to fear of Santa Anna and then joined the US because the Republic of Texas was broke and constantly in danger of a Mexican reconquest. The fledgling country even had important foreign representation and one can imagine a British protectorate emerging without vigorous US attempts to annex the Republic. It's not like the situation of white settlers in the Kingdom of Hawaii.
So it wasn't a culture bomb that loosened Texas from Mexico, it was poor leadership and political tyranny from Mexican leaders.
