U.S. – Rio Grande River Mexico – Nueces River U.S. believed in Manifest Destiny This was the belief that America should own all the land “sea to shining sea,” from the east coast to the west. They felt it was their God Given Right… their destiny.

3. This painting shows Manifest Destiny as a religious belief that the United States should expand from the Atlantic Ocean to the Pacific Ocean in the name of God. In 1872 artist John Gast painted a popular scene of people moving west that captured the view of Americans at the time. Called "Spirit of the Frontier“, the painting portrays settlers moving west, guided and protected by a goddess-like figure of Columbia and aided by technology (railways, telegraphs), driving away Native Americans and bison in the process. It is also important to note that angel is bringing the "light" as witnessed on the eastern side of the painting as she travels towards the "darkened" west.
