The Black Hawk Purchase, also known as the Forty-Mile Strip or Scott's Purchase, extended along the West side of the Mississippi River from the north boundary of Missouri North to the Upper Iowa River in the northeast corner of Iowa. It was fifty miles wide at the ends, and forty in the middle, and is sometimes called the "Forty-Mile Strip". The land, originally owned by the Sauk, Meskwaki (Fox), and Ho-Chunk (Winnebago) Native American people, was acquired by treaty following their defeat by the United States in the Black Hawk War. After being defeated the Sauk and Mesquakie were forced to relinquish another 2.5 million hectares or (6 million acres) and give up their rights to plant, hunt, or fish on the land. The purchase was made for $640,000 on September 21, 1832 and was named for the chief Black Hawk, who was held prisoner at the time the purchase was completed. The Black Hawk Purchase contained an area of 6 million acres (24,000 km²), and the price was equivalent to 11 cents/acre ($26 per km²). The region is bounded on the East by the Mississippi River and includes Dubuque, Fort Madison, and present-day Davenport. About The treaty was made by General Winfield Scott and the Governor of Illinois, John Reynolds, at what is now Davenport, Iowa, on the west bank of the Mississippi River. The agreement was ratified February 13, 1833, and officially went into effect on June 1, 1833, when the territory became the first section of what is now Iowa to be opened for settlement by non-Native Americans: United States citizens, or Europeans.
