That's the question Tom Cordlle asks in his comment on the Johnny Robish post:
"The Republic of Texas came into the union In 1845 with a minority white population.
American Indians, Mexicans, and African-American slaves held a numerical majority until the influx of whites pushed the Indians and Mexicans out of the territory and slavery became limited by the Missouri Compromise in 1852....
None of this is made obvious or clear in standard public school history texts.
The fact is, Texas practiced repressive and oppressive apartheid before the 1867 discovery of diamond deposits in South Africa....
And, in many respects, does so to this day...."
