This paper looks at "Manifest Destiny" , a reference to the inevitable
expansion of the territorial boundaries of the United
States
westward to the Pacific Ocean and beyond. It discusses how the concept of "Manifest Destiny" was frequently used by American expansionists to justify the U.S. annexation of Texas, Oregon, New Mexico, California, and later U.S. involvement in Alaska, Hawaii, and the Philippines. It provides an examination of the factors that influenced the
expansion of the country westward during the 1840s and 1850s, followed by a summary of the research in the conclusion.
