3 themes were used to promote the expansion of the American Empire in the 19th century.
1. the virtue of the American people and their institutions;
2. the mission to spread these institutions, thereby redeeming and remaking the world in the image of the U.S;
3. the destiny under God to accomplish this work.
Thomas Paine wrote in Common Sense:
We have it in our power to begin the world over again. A situation, similar to the present, hath not happened since the days of Noah until now. The birthday of a new world is at hand...Many Americans agreed with Paine, and came to believe that the United States had embarked upon a special experiment in freedom and democracy—and a rejection of Old World monarchy in favor of
republicanism—an innovation of world historical importance.
Lincoln opposed Southern sectionalism, anti-immigrant nativism, and the imperialism of Manifest Destiny as both unjust and unreasonable. He believed each of these disordered forms of love threatened the inseparable moral and fraternal bonds of liberty and Union that he sought to perpetuate through a patriotic love of country guided by wisdom and critical self-awareness.

Definition of republicanism (in those days)It stresses
liberty and rights as central values, makes the people as a whole sovereign, rejects inherited political power, expects citizens to be independent in their performance of civic duties, and vilifies corruption...
It is not the same as democracy(majority rule), for republicanism asserts that people have unalienable rights that cannot be voted away by a majority of voters.http://en.wikipedia.org/wiki/Republicanism_in_the_United_StatesWhat the hell happened?!
