The Trans-Mississippi and International Exposition, also known as the Omaha Worlds Fair, was a grand world’s fair held in Omaha, Nebraska, from June 1 to November 1, 1898. Often referred to as the Omaha World's Fair, its primary goal was to showcase the rapid development and economic recovery of the American West following the financial panic of 1893.

Key Features & Attractions
The Grand Court: The heart of the 184-acre site featured a two-thousand foot-long lagoon designed to resemble Venetian canals hosted gondola rides as a whimsical form of transportation throughout the fair.
The "White City": Like the 1893 Chicago World’s Fair, the buildings were constructed of staff (a mixture of plaster and horsehair) and painted white, giving them a marble-like appearance. Designed in Renaissance style reflected ancient Greek and Roman influences and possessed strenuous constraints on color, scale and height. All was built out of cheap materials or designed not to last, at the end of the exposition it was all removed.
Electrical Illumination: One of the most stunning features was the use of over 20,000 electric light bulbs to illuminate the fairgrounds and lagoon at night—a brand-new marvel at the time.
Indian Congress: A massive gathering of over 500 Native Americans from 35 different tribes, including notable figures like Apache leader Geronimo.
Entertainment: Visitors enjoyed carnival rides, a giant seesaw, and Buffalo Bill Cody's Wild West show
