What actions did Texans take to reform their politics, economy, geography, and society?

Texas had a mixed heritage in the 19th century that was thoroughly Americanized.

Explanation:

Texas was a place that had traded hands of power for a few times in the past.

One of this was the time when the Spanish occupied it for long, then there were the days of the Mexicans.

Then Texas was also an independent state for a while until it merged with the US.

What followed was a quite aggressive front of assimilation of Texans and their Hispanic culture into the US.

In a century Texas was almost the poster boy of Southern America with its values and enshrinement of those tenets in its core values.
