Step-by-step explanation:
The manifest destiny is a concept that is attributed to the ideal of the first American settlers about the new nation that was being formed and its expansionist plans. In particular, he explains how this country understands its place in the world and relates to other peoples, as well as creates the national conviction that God chose the United States to be a political and economic power, a superior nation. The phrase "Manifest Destiny" first appeared in an article written by journalist John L. O'Sullivan, in 1845, in the New York Democratic Review magazine. In his article, O'Sullivan explained the reasons for the necessary territorial expansion of the United States and supported the annexation of Texas. From this assumption, the United States annex the territories California and Texas and invade Mexico, in what would be the Mexico / United States war. As a result, the United States appropriates Arizona, Colorado, Nevada, New Mexico, Utah and parts of Wyoming, Kansas and Oklahoma.
