What impact did industrialization have on western migration

United States grew drastically, in power and in geographical size. The Louisiana Purchase more than doubled the nation's size and opened up a little known region to exploration and eventual settlement. Soon, explorers were returning from forays into the wilderness with stories of great stretches of beauty and fertile land. Some Americans ventured westward, but the nation was largely consumed by its struggle to maintain its neutrality in the face of threats from Britain and France. The War of 1812 settled this issue, leaving the United States free to pursue North American goals. The nation turned its attention to the issue of expansion. The founding fathers had envisioned the United States as a bastion of freedom that would cover territory reaching all the way across the North American continent
