It is difficult to put an exact date to the beginning of Manifest Destiny because it was a long process. The term itself does have a definite beginning. Journalist John L. O’Sullivan coined the phrase in 1845 to help drum up support for the annexation of Texas and the Oregon Country into the United States. Taken literally, the term means the obvious will of God. In essence, the term means that it was clearly a divinely inspired plan for America to expand from sea to shining sea, no matter what it took or who was in the way. O’Sullivan may have given the phenomenon a moniker, but Manifest Destiny was in full swing long before that.
