When John O'Sullivan wrote in 1845, "...the right of our manifest destiny to overspread and to possess the whole of the continent which Providence has given us for the development of Liberty and federated self-government entrusted to us", he coined a phrase that aptly describes how Americans from colonial days and into the twentieth century perceived their privileged role. Anders Stephanson examines the consequences of this idea over more than three hundred years of history, as Manifest Destiny drove the westward settlement to the Pacific, defining the stubborn belief in the superiority of white people and denigrating Native Americans and other people of color. He considers it a component in Woodrow Wilson's campaign "to make the world safe for democracy" and a strong factor in Ronald Reagan's administration.
