Manifest Destiny
Manifest Destiny was a phrase which invoked the idea of divine sanction for the territorial expansion of the United States. It first appeared in print in 1845, in the July-August issue of the United States Magazine and Democratic Review. The anonymous author, thought to be its editor John L. O'Sullivan, proclaimed "our manifest destiny to overspread the continent allotted by Providence for the free development of our multiplying millions."
The specific context of the article was the annexation of Texas, which had taken place not long before. Other applications of the notion of manifest destiny were soon found. It was used to promote the annexations of Mexican territory acquired in the Mexican-American War, of territory in Oregon gained through negotiations with the British, and the seizure (not carried out) of Cuba from the Spanish during the 1850's.
