Topics: Omaha, Nebraska - Wikipedia
Various Native American tribes had lived in the land that became Omaha, including since the 17th century, the Omaha and Ponca , Dhegian-Siouan-language people who had originated in the lower Ohio River valley and migrated west by the early 17th century; Pawnee , Otoe , Missouri , and Ioway. The word Omaha (actually Umoⁿhoⁿ or Umaⁿhaⁿ ) means "Dwellers on the bluff". 
Through 26 separate treaties with the United States federal government, Native American tribes in Nebraska gradually ceded the lands currently comprising the state. The treaty and cession involving the Omaha area occurred in 1854 when the Omaha Tribe ceded most of east-central Nebraska.  Logan Fontenelle , an interpreter for the Omaha and signatory to the 1854 treaty, played an essential role in those proceedings.
Equally as important, the Union Stockyards were founded in 1883.  Within twenty years of the founding of the Union Stockyards in South Omaha, four of the five major meatpacking companies in the United States were located in Omaha. By the 1950s, half the city's workforce was employed in meatpacking and processing. Meatpacking, jobbing and railroads were responsible for most of the growth in the city from the late 19th century through the early decades of the 20th century.
