"We must onward to the fulfilment of our mission - to the entire development of the principle of our organization - freedom of conscience, freedom of person, freedom of trade and business pursuits, universality of freedom and equality. This is our high destiny, and in nature's eternal, inevitable decree of cause and effect we must accomplish it. All this will be our future history, to establish on earth the moral dignity and salvation of man - the immutable truth and beneficence of God.

Key Concept

KC-5.1.III: The idea of Manifest Destiny, which asserted U.S. power in the Western Hemisphere and supported U.S. expansion westward, was built on a belief in white racial superiority and a sense of American cultural superiority, and helped to shape the era’s political debates.

Explanation

The concept of Manifest Destiny, as articulated by John L. O'Sullivan, was a belief that the United States was destined to expand across the continent. This belief was a significant driving force behind the rapid expansion of the United States during the mid-19th century. One of the major consequences of Manifest Destiny was the conflict with Mexico, known as the Mexican-American War (1846-1848). The U.S. desire to acquire Texas and other territories in the Southwest led to this war. Therefore, option C is the correct answer.

What was the Mexican-American War?

The Mexican-American War was a conflict between the United States and Mexico that took place from 1846 to 1848. It began as a result of unresolved border disputes between the U.S. and Mexico after the U.S. annexation of Texas. The war ended with the Treaty of Guadalupe Hidalgo, in which Mexico ceded a large portion of its northern territories to the U.S., including present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado, Wyoming, Kansas, and Oklahoma. This significantly expanded the size of the U.S. and led to further conflict over the expansion of slavery into these new territories.
