To what extent did manifest destiny and territorial expansion unite or divide the united states from 1830 to 1860 dbq

     The "Manifest Destiny" is a representation of an idea that justifies United States massive expansion throughout the 19th Century. It states that it was part of the plans of God that the  United States, as a superior, dominated all of America, and the Americans of the United States were blessed. There was a national feeling of accomplishment and a political tendency of Economic Nationalism.

     The expansion started with the Westward settlement of Americans and by the support of the 1787 Northwest Ordinance, there was the possibility of annexation of new states. Since then, the United States had a significant growth of its original territory, mainly through the following ways:

     The annexation of the new states implied that they were settled in a condition of "Free" or "Slave" state, according to the region they and the politics of the place. This, along with the different political views and need of homogeneity of federal decisions (a feeling that the North was benefited by federal laws and decisions.) created a sectarian feeling on the country that led later to the separation of the United States of America (Northern, predominately free states)  to the Confederate States of America (predominately slave states), and ultimately led to the Civil war in the 1860's

     We can say Manifest Destiny united the people of United States in a general feeling of prosperity, in a kind of religious way, but divided the states itself , because of the need of the new states "identity" to be determined.

The concept that the United States is destined—by God, according to its campaigners expand its control and propagate democratic socialism across the whole American continent is known as Manifest Destiny, a term coined in 1845.

The United States had gone all-out war with Mexico by the time the Oregon dispute was resolved, driven by the spirit of Manifest Destiny and territorial ambition.

The Treaty of Guadalupe Hidalgo, which ended the Mexican-American War in 1848, granted the United States an additional 525,000 square miles of land, including all or parts of what became

Despite Manifest Destiny's lofty ideals, the United States' rapid territorial expansion during the first half of the nineteenth century resulted in the displacement and brutal mistreatment of Native Americans, Hispanics, and other non-European occupants of the territories now occupied by the United States.

The rising controversy over slavery was exacerbated by the United States' growth, which posed the pressing question of whether new states admitted to the Union would tolerate slavery or not—a dispute that would eventually lead to the Civil War.
