how would the concept of free development be carried out as part of manifest destiny
Manifest destiny Six years later, in 1845, O'Sullivan wrote another essay titled Annexation in the Democratic Review,[17] in which he first used the phrase manifest destiny.[18] In this article he urged the U.S. to annex the Republic of Texas,[19] not only because Texas desired this, but because it was "our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions".[20] Overcoming Whig opposition, Democrats annexed Texas in 1845. O'Sullivan's first usage of the phrase "manifest destiny" attracted little attention.[21]
