For more information on this famous painting, please see this online piece from Martha Sandweiss

Origins of the term “manifest destiny” (1845)
On Texas (July 1845)
“…other nations have undertaken to intrude themselves into it, between us and the proper parties to the case, in a spirit of hostile interference against us, for the avowed object of thwarting our policy and hampering our power, limiting our greatness and checking the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.”
–Excerpted from John L. O’Sullivan, “Annexation,” The United States Magazine and Democratic Review 17 (July 1845): 5–10
