constantly occurring, which have continued to increase our causes of complaint and to swell the amount of our demands.  While the citizens of the United States were conducting a lawful commerce with Mexico under the guaranty of a treaty of “amity, commerce, and navigation,” many of them have suffered all the injuries which would have resulted from open war.  This treaty, instead of affording protection to our citizens, has been the means of inviting them into the ports of Mexico that they might be, as they have been in numerous instances, plundered of their property and deprived of their personal liberty if they dared insist on their rights.  Had the unlawful seizures of American property and the violation of the personal liberty of our citizens, to say nothing of the insults to our flag, which have occurred in the ports of Mexico taken place on the high seas, they would themselves long since have constituted a state of actual war between the two countries.  In so long suffering Mexico to violate her most solemn treaty obligations, plunder our citizens of their property, and imprison their persons without affording them any redress we have failed to perform one of the first and highest duties which every government owes to its citizens, and the consequence has been that many of them have been reduced from a state of affluence to bankruptcy.  The proud name of American citizen, which ought to protect all who bear it from insult and injury throughout the world, has afforded no such protection to our citizens in Mexico.  We had ample cause of war against Mexico long before the breaking out of hostilities; but even then we forbore to take redress into our own hands until Mexico herself became the aggressor by invading our soil in hostile array and shedding the blood of our citizens.

Such are the grave causes of complaint on the part of the United States against Mexico—­causes which existed long before the annexation of Texas to the American Union; and yet, animated by the love of peace and a magnanimous moderation, we did not adopt those measures of redress which under such circumstances are the justified resort of injured nations.

The annexation of Texas to the United States constituted no just cause of offense to Mexico.  The pretext that it did so is wholly inconsistent and irreconcilable with well-authenticated facts connected with the revolution by which Texas became independent of Mexico.  That this may be the more manifest, it may be proper to advert to the causes and to the history of the principal events of that revolution.

Texas constituted a portion of the ancient Province of Louisiana, ceded to the United States by France in the year 1803.  In the year 1819 the United States, by the Florida treaty, ceded to Spain all that part of Louisiana within the present limits of Texas, and Mexico, by the revolution which separated her from Spain and rendered her an independent nation, succeeded to the rights of the mother country over
