I believe the Federalists opposed a Bill of Rights because they claimed that it was already implied in the Constitution. I can’t think of anything else though. Sorry.
The full faith and credit clause deals with legal proceedings between states.
During that period local rulers, either powerful families or military<span> warlords, dominated the land, while the emperor was merely a figurehead and not a significant political presence. Society was divided into two main classes in Feudal Japan, the nobility and the peasants.</span>
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
