The portion marked in yellow indicates the area of the Black Hawk Purchase.

BLACK HAWK PURCHASE. The Black Hawk Purchase was a land acquisition made in what is now Iowa by the United States federal government.

The land originally owned by the SAUK AND FOX, and Ho-Chunk (WINNEBAGO) was acquired by treaty following their defeat by the United States in the Black Hawk War. The purchase was made for $640,000 on September 21, 1832 and was named for the chief Black Hawk. He was held prisoner at the time the purchase was completed. The Black Hawk Purchase contained an area of some 6 million acres and the price was equivalent to 11 cents per acre.
