Description: This map shows the formation of states up until 1800. It reveals the major political boundaries prior to the Louisiana Purchase. "The first new state admitted was Vermont, in 1791, and the last were New Mexico and Arizona, which came into the Union in 1912. At the organization of the government, the Mississippi River formed the western boundary of the United States, and the area of the country was 828,000 square miles." — Foster, 1921
