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."
