The history of Omaha, Nebraska began before the settlement of the city, with speculators from neighboring Council Bluffs, Iowa staking land across the Missouri River illegally as early as the 1840s. Before it was legal to claim land in Indian Country, William D. Brown was operating the Lone Tree Ferry to bring settlers from Council Bluffs to Omaha. A treaty with the Omaha Tribe allowed the creation of the Nebraska Territory, and Omaha City was founded on July 4, 1854. With early settlement came claim jumpers and squatters, and the formation of a vigilante law group called the Omaha Claim Club, which was one of many claim clubs across the Midwest. During this period many of the city's founding fathers received lots in Scriptown, which was made possible by the actions of the Omaha Claim Club. The club's violent actions led to the U.S. Supreme Court trial, Baker v. Morton, which led to the end of the organization.
Surrounded by small towns and cities that competed for business from the hinterland's farmers, the city suffered a major setback in the Panic of 1857. Despite this, Omaha quickly emerged as the largest city in Nebraska. After losing the Nebraska State Capitol to Lincoln in 1867, many business leaders rallied and created the Jobbers Canyon in downtown Omaha to outfit farmers in Nebraska, South Dakota, Wyoming and further west. Their entrepreneurial success allowed them to build mansions in Kountze Place and the Old Gold Coast neighborhoods.
