The Louisiana Purchase was the acquisition by the United States of about 530,000,000 acres (828,000 sq mi or 2,100,000 km²) of territory from France in 1803, at the cost of about 3¢ per acre (7¢ per ha); totaling US$15 million or ₣80 million. Including interest, America finally paid $23,213,568 for the Louisiana territory.http://www.blm.gov/natacq/pls02/pls1-1_02.pdf Table 1.1 Acquisition of the Public Domain 1781-1867 The land purchased contained all of present-day Arkansas, Missouri, Iowa, Oklahoma, Kansas, Nebraska, Minnesota south of Mississippi River, much of North Dakota, nearly all of South Dakota, northeastern New Mexico, northern Texas, the portions of Montana, Wyoming, and Colorado east of the Continental Divide, and Louisiana on both sides of the Mississippi River, including the city of New Orleans.
