US Presidency
1851

It is gratifying, not only to those who consider the commercial interests of nations, but also to all who favor the progress of knowledge and the diffusion of religion, to see a community emerge from a savage state and attain such a degree of civilization in those distant seas. It is much to be deplored that the internal tranquillity of the Mexican Republic should again be seriously disturbed, for since the peace between that Republic and the United States it had enjoyed such comparative repose that the most favorable anticipations for the future might with a degree of confidence have been indulged. These, however, have been thwarted by the recent outbreak in the State of Tamaulipas, on the right bank of the Rio Bravo. Having received information that persons from the United States had taken part in the insurrection, and apprehending that their example might be followed by others, I caused orders to be issued for the purpose of preventing any hostile expeditions against Mexico from being set on foot in violation of the laws of the United States.
