The principal cause of this feeling--the supposed misconduct of our government in the settlement, revolution and successful resistance of Texas, and in the recognition and annexation of that republic--has already been explained; but other strong reasons coöperated. All understood that intense dissatisfaction existed in the northern departments. Now that our frontier had been advanced so far south, further peaceful aggression seemed easy; and it was believed that we intended to pursue the Texas method progressively, until all of Mexico should little by little become ours. "This first invasion is the threat of many more," said the official journal. It was alleged that we, fearing the competition of that country in the markets of the world, did all we could to hinder its agricultural, industrial and commercial development, and excited the revolutions that paralyzed it; and it was even believed that we incited the Indians to ravage the northern frontiers, and so create discontent against the central government. The privileged classes dreaded the influence of our democratic ideas. The clergy were afraid that Protestantism, or at least free thought, might cross the border, and that so far as Mexican territory should fall under our sway, secular education, the confiscation of their property, and the other anti-clerical plans of the Federalists, who appeared to draw their inspiration and their arguments largely from this country, might be put into force. The numerous misunderstandings and clashes with the United States that we have noted had produced an enduring resentment, and in particular our claims and our efforts to have them settled were commonly deemed artificial and unjust.[5.1]
