Little Hawk,

You only need to adjust your way of thinking a little and you will be nearer the Truth.

Think of the northern 40% of what is now Mexico as Indian Territory. No different than the rest of North America, Canada included.

These Indian tribes were historically bullied by the true Mexicans who were native to the plateau area around Mexico City.

Many tribes including the Kikapoo (Texas), the Papago (Arizona) and the Apache were divided when the border between the US and Mexico was finalized (see Gadsden Purchase).

The Spanish were bad enough, bringing disease and forcing the conversion to Roman Catholicism, but the Meijas were intolerable. The California and Texas Indians joined the Anglos and most Spanish in rejecting the claims that the new (1821) Mexican independant government made. The despute lasted from 1821- 1853 when a treaty was signed.
