Where did manifestdestiny happen?

Manifest Destiny primarily occurred in the United States during the 19th century, particularly from the 1840s to the 1850s. It involved the westward expansion of the U.S. across North America, encompassing territories that included present-day California, Oregon, and Texas. This belief in the nation's inevitable expansion was fueled by a combination of economic interests, a desire for land, and a sense of American exceptionalism. The doctrine significantly impacted relations with Indigenous peoples and neighboring countries, particularly Mexico.
