The capital of the United States is established at Washington, D.C., a new city located at the junction of the Potomac and Anacostia rivers. The nation expands rapidly in the early nineteenth century, most notably with the purchase of Louisiana (from Napoleon for about $15 million), which doubles the size of the country. With the founding, early in the century, of the American Academy of the Fine Arts (New York) and the Pennsylvania Academy of the Fine Arts (Philadelphia), and later The Metropolitan Museum (New York) and the Museum of Fine Arts (Boston), the nation’s artistic roots are sown.
