Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. This is a simplified list of United States territorial acquisitions, beginning with American independence. Note that this list primarily concerns land acquired from other nation-states; the numerous territorial acquisitions from American Indians are not listed here.The 1783 Treaty of Paris with Great Britain defined the original borders of the United States. Due to ambiguities in the treaty, the ownership of Machias Seal Island and North Rock remains disputed between the U.S. and Canada; other original territorial ambiguities (including the Northeastern Boundary Dispute and the disputed Indian Stream territory) were resolved by the Webster-Ashburton Treaty in 1842.The Louisiana Purchase, completed in 1803, was negotiated by Robert Livingston during the presidency of Thomas Jefferson; the territory was acquired from France for $15,000,000 (equivalent to $219 million in present day terms).
