John L. O’Sullivan coined the term Manifest Destiny
in 1845 while advocating for the annexation of Texas. It came to be defined as the belief that God had given the US the special calling and privilege of spreading its civilization and Christianity across the whole of the North American continent, moving westward from the Atlantic to the Pacific.
You should know a few areas out west and what drew settlers there during the time of Manifest Destiny:
You should also know some of the impacts of Manifest Destiny on the people out west and the US as a whole:
While Manifest Destiny is mostly associated with the westward expansion of the US in the antebellum (pre-Civil War) era, the term also applies to later westward expansion efforts such as the Homestead Act of 1862 that gave away land out west to American settlers. It also later fueled the US overseas expansion during the 1890s (see Period 7) and beyond.
