Manifest Destiny

• Manifest Destiny, a term coined by journalist John O'Sullivan in 1845, encapsulated the belief that US expansion was inevitable and divinely ordained
• Proponents argued that spreading democracy, Christianity, and American values across the continent was a moral obligation

• Critics argued that Manifest Destiny was a thinly veiled excuse for imperialism and the displacement of Native Americans
• Manifest Destiny shaped US foreign policy and led to the annexation of Texas, Oregon Country, and the Mexican Cession
