The green-shaded area represents the territory acquired by the United States from France in 1803 for $15 million-approximately 828,000 square miles. It encompassed all or part of 15 present-day U.S. states, including Louisiana, Arkansas, Missouri, Iowa, Oklahoma, Kansas, Nebraska, and parts of Minnesota, North Dakota, South Dakota, New Mexico, Texas, Colorado, Wyoming, and Montana. This acquisition dramatically reshaped American geography and fueled westward expansion.
