Manifest Destiny

How Manifest Destiny Helped to Spread Democracy and Capitalism in America

The idea of Manifest Destiny was an important part of American History. It was a belief that the United States had a divinely-ordained mission to spread democracy and capitalism across the entire continent.


This belief played a significant role in the territorial expansion of the United States in the 19th century, and it helped to shape the country into what it is today.

In this article, we’ll explore how Manifest Destiny helped to spread democracy and capitalism in America.


What Is Manifest Destiny?

Manifest Destiny was the 19th-century belief that the United States was destined to expand from “sea to shining sea.”

The concept was based on the idea of American exceptionalism, with many in the US believing that it was God’s will for them to establish a new nation and spread their values across the continent.

The term was first coined by journalist John L. O’Sullivan in 1845 when he wrote of the United States’ mission to “overspread and to possess the whole of the continent which Providence has given us for the development of the great experiment of liberty and federated self-government entrusted to us.”

Polk’s administration, who famously declared that “the fulfilment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.”

Manifest Destiny played a large role in the formation of the United States as we know it today, as it led to the acquisition of new land through the Oregon Treaty and other policies driven by Polk’s nationalism.


The Role of Religion

Religion played an important role in helping to spread the concept of Manifest Destiny. During James K. Polk’s presidency, he championed the idea of extending American rule by invoking the imagery of the Biblical Promised Land.


Polk used a combination of his nationalism, religious fervour, and a desire for economic expansion as motivators for acquiring new territory. Through the Oregon Treaty of 1846, America was able to acquire a great deal of land from the British government, greatly expanding its borders.

Though some saw the treaty as unethical, Polk’s supporters argued that it was divinely ordained for America to gain more land and spread democracy across the continent.

This religious fervour inspired settlers to migrate westward, driven by the idea that it was their God-given mission to do so. As Manifest Destiny continued to expand America, religion served to encourage it rather than to oppose it.

The Role of Economics

Economics played an important role in James K. Polk’s Manifest Destiny agenda, It was central to his goal of expanding the United States’ borders and solidifying the nation’s presence on the continent.

The Oregon Treaty of 1846 was a particularly important step in this process, as it helped the United States to secure lands in the Pacific Northwest, expand its influence over the West, and establish its claim to a large portion of the continent.

This treaty was a cornerstone of Polk’s nationalism, which relied heavily on economic factors such as land acquisition and trade policy.

The Role of Politics

Throughout American history, politics have played an important role in the spread of Manifest Destiny.

The concept of Manifest Destiny popularized by President James K. Polk’s nationalism and vision of America as a great power led to numerous acquisitions, including the Oregon Treaty and the Mexican-American War.
