In 1845 John L. O'sullivan authored the expression "show fate" in reference to a developing conviction that the United States was predetermined by God to stretch all through North America and activity administration over its neighbors. In the United States Magazine and Democratic Review (July–august 1845, p. 5) he contended for "the satisfaction of our show predetermination to overspread the mainland distributed by Providence for the free improvement of our yearly increasing millions." Around the time of O'sullivan's composition, the United States saw a phenomenal regional development of 1.2 million square miles, an amplification of more than 60 percent. The vast majority of this development happened to the detriment of the recently autonomous Mexico and the Native American countries. The extension happened at such a quickened pace, to the point that individuals like O'sullivan felt that significantly bigger developments were inescapable, essential, and alluring henceforth the beginning of the idea of show fate.
