Question

What were the reasons for the late nineteenth century boom on migration to the West from the eastern United States and Europe?

Answer 1

Okay, so, just from the top of my head, I think that it is because of the growing belief of "Manifest Destiny" in the nineteenth century.  I'm not sure if this is the actual right answer for your question, but I do know that Manifest Destiny was in the nineteenth century and was the widely held belief in the USA that American settlers were destined to expand through out the continent.  And I think both the USA and Europe wanted to expand, it was kind of a copetition/conflict they had.  This was actually how Canada and Alaska came to be I believe.  This was a simple explanation btw. cx
