What is not a part of the Western Expansion from 1840 to 1880?

The Western Expansion in the United States from 1840 to 1880 encompasses a period in which there was significant growth and exploration westward, particularly beyond the Mississippi River. Key events and developments during this era involved the concept of Manifest Destiny, the acquisition of new territories, the displacement of Native American tribes, the gold rush, the construction of railroads, and the settlement of new states. However, something that would not be part of the Western Expansion from 1840 to 1880 includes:

The establishment of the original 13 colonies, which occurred much earlier, in the late 17th and 18th centuries. - The Civil War (1861-1865), although it did occur during a portion of this period, it was predominantly an event separate from the motives and activities specific to Western Expansion. - The Industrial Revolution’s beginnings, which primarily started in the late 18th century in Britain and the northeastern U.S., not the western territories. - The purchase of Alaska from Russia in 1867, while still part of American territorial expansion, is generally not considered part of the contiguous western frontier expansion as it is not part of the contiguous United States nor part of the westward movement patterns followed by settlers, miners, and others in the given timeframe.
