Share. By Steve Jones. The term Manifest Destiny, which American writer John L. O'Sullivan coined in 1845, describes what most 19th-Century Americans believed was their God-given mission to expand westward, occupy a continental nation, and extend U.S. constitutional government to unenlightened peoples.he term Manifest Destiny fell out of use after the U.S. Civil War, in part to racist overtones of the concept, but it returned again in the 1890s to justify American intervention in the Cuban rebellion against Spain. That intervention resulted in the Spanish-American War, 1898.
