Preceding Context: In 1803 President Thomas Jefferson obtained from France the Louisiana Purchase for fifteen million dollars (equivalent to about $230 million today) which included all the land drained by the Missouri River and roughly doubled the size of U.S. territory. The future states of Iowa and Missouri, located west of the Mississippi River and east of Missouri River, were part of this purchase. The Lewis and Clark Expedition stopped several times in the future state of Iowa on their 1805–1806 expedition to the west coast. A disputed 1804 treaty between Quashquame and William Henry Harrison (future ninth President of the U.S.) that surrendered much of the future state of Illinois to the U.S. enraged many Sauk (Sac) Indians and led to the 1832 Black Hawk War. As punishment for the uprising, and as part of a larger settlement strategy, treaties were subsequently designed to remove all Indians from Iowa Territory. Some settlers started drifting into Iowa in 1833. President Martin Van Buren on July 4, 1838, signed the U.S. Congress laws establishing the Territory of Iowa. Iowa was located opposite the junction of the
Succeeding Context: and Missouri Rivers and was used by some of the Fur trapper rendezvous traders as a starting point for their supply expeditions. In 1846 the Mormons, expelled from Nauvoo, Illinois, traversed Iowa (on part of the Mormon Trail) and settled temporarily in significant numbers on the Missouri River in Iowa and the future state of Nebraska at their Winter Quarters near the future city of Omaha, Nebraska. (See: Missouri River settlements (1846–1854)) The Mormons established about 50 temporary towns including the town of Kernsville Iowa (renamed Council Bluffs, Iowa in 1852) on the east bank of the Missouri River opposite the mouth of the Platte River. For those travelers to Oregon, California, and Utah who were bringing their teams to the Platte River junction Kernsville and other towns become major "jumping off places" and supply points. In 1847 the Mormons established three ferries across the Missouri River and others established even more ferries for the spring start on the trail. In the 1850 census there were about 8,000 mostly Mormons tabulated in the large Pottawattamie County, Iowa District 21. (The original Pottawattamie County was subsequently made into five counties and parts of several more.) By 1854 most of the Mormon towns, farms and villages were largely taken over by non-Mormons as they abandoned them or sold them for not much and continued their migration to Utah. After 1846 the towns of Council Bluffs, Iowa, Omaha, Nebraska (est. 1852) and other Missouri River towns became major supply points and "jumping off places" for travelers on the Mormon, , Oregon and other trails west.
