Omaha's pioneer period began in 1854, when the city was founded along the Missouri River by speculators from neighboring Council Bluffs, Iowa. It originally comprised a crossing called Lone Tree Ferry earning the city its nickname, the "Gateway to the West". Omaha introduced this new West to the world in 1898, when it played host to the World's Fair, dubbed the Trans-Mississippi Exposition. During the 19th century, Omaha's central location in the United States spurred the city to become an important national transportation hub. Throughout the rest of the 19th century, the transportation and jobbing sectors were important in the city, along with its railroads and breweries. In the 20th century, the Omaha Stockyards, once the world's largest, and its meatpacking plants gained international prominence.

Council Bluffs is a city in and the county seat of Pottawattamie County, Iowa, United States. Located on the east bank of the Missouri River, it sits across from Omaha, Nebraska. The city had a population of 62,799 at the 2020 census, making it the tenth-most populous city in Iowa and the largest in Southwest Iowa. Council Bluffs is also a principal city in the Omaha–Council Bluffs metropolitan area.

Until about 1853, Council Bluffs was known as Kanesville. Kanesville was the historic starting point of the Mormon Trail. Kanesville is also the northernmost anchor town of the other emigrant trails because there was a steam-powered boat which ferried the settlers' wagons and cattle across the Missouri River. In 1869, the first transcontinental railroad to California was connected to the existing U.S. rail network at Council Bluffs.
