We continually meet with the phrases in newspapers, English and American, and especially in Mexican documents, “the robbery and plunder of Mexico, of her province of Texas,” and of the “ingratitude of the people of Texas.” These expressions, from frequent use, have come to have some meaning attached to them with those who are not acquainted with the true history of the case. Now what is Mexico, and what particular right had she ever to Texas? She was once a vice-royalty of Spain, composed of various Intendencies, or local and subordinate Governments. These Intendencies, taking advantage of the troubles of old Spain, set up for themselves, and endeavored to throw off the Spanish dominion, practising the same thing that Texas has done as respects Mexico; and if Texas has been ungrateful to Mexico, for the same reason Mexico has been ungrateful to Spain. But the struggle for independence was carried on by them separately, and independently of each other; not united like the British Colonies in the Revolutionary War. It may be new to some to be told that Texas not only achieved her own independence without the aid of any Mexican Province or Intendency, but was actually the means, through the Americans then inhabiting the country, with the aid of citizens of the United States, of enabling the other Mexican Provinces to gain _their_ independence. Before I am done this will be demonstrated. Mexico owes a debt to the American people of Texas and of the United States, for her independence, _if it be worth anything_, and, consequently, the ingratitude is on her side. But her efforts were finally successful through the treachery of Iturbide. He was a traitor to Spain, in whose employment he was, and by one of those military revolts, since of daily recurrence in the mis-named Republic of Mexico, overturned the Spanish authority, and proclaimed himself Emperor! The empire was soon after overturned by something approaching nearer to a popular revolution in the Intendencies or Provinces. An attempt at something like a Republic, followed the downfall of the Emperor. States were formed out of the Intendencies, and a confederated Republic, in imitation of the United States, was established in form, but in form only. Texas, with parts of two other Intendencies, was constituted one of these States. The confederated Republic was not long lived. It fell to pieces or was overturned by the military chiefs, and then each State, was again compelled to look out for itself. Some submitted, some were subdued by this military power, the only real power; and others still retain their preference for the federative system, although compelled to submit to the central authority. The only one which _did not submit to the overthrow of the Constitution by a military usurper, was ungrateful Texas_.
