The following list of treaties is composed of treaties which have names (as referenced in other treaties, letters, etc).
Thomas Jefferson—like many other Republicans—had a vision of an America composed of many, small, land-owning farmers and expanded popular participation in elections. The Louisiana Purchase (1803) allowed Jefferson to implement this vision through what he called the Empire of Liberty. He did not view this as an empire of conquest (like the empires of Spain, France, and England). The terminology “empire of liberty” comes from the notion that the United States can spread liberty to other places through its territorial expansion. This ideology was not much different than colonization.
