The history of Omaha Nebraska begins with Indigenous homelands, the Missouri River, westward migration, and the railroads. Located in Douglas County along Nebraska’s eastern border, Omaha grew beside an important Missouri River crossing. Railroads, livestock, meatpacking, immigration, and commerce later transformed the city.
Indigenous peoples lived throughout the Missouri River region long before Omaha existed. The Omaha, Otoe-Missouria, and Pawnee nations, among others, lived, hunted, and traveled across the area. Rivers, prairies, and woodlands supported farming, trade, and travel.
The city takes its name from the Omaha Tribe. The name means “people going against the current.” In 1854, the Omaha Tribe ceded most of east-central Nebraska to the United States by treaty, and Chief Logan Fontenelle signed it. As a result, the city’s name reflects a much older Indigenous history.
The Missouri River became central to Omaha’s location and growth. William D. Brown began running the Lone Tree Ferry across the river in 1850. In 1853, a group formed the Council Bluffs and Nebraska Ferry Company, which owned property on both sides of the water. Ferries and steamboats carried travelers and goods until 1872, when Union Pacific opened the first bridge across the river.
Council Bluffs, Iowa, grew up on the opposite bank, along westward migration routes. Its merchants and speculators saw the promise of the western shore. Soon, the ferry company surveyed a townsite on the Nebraska side.
The Kansas-Nebraska Act created Nebraska Territory on May 30, 1854. That summer, surveyor Alfred D. Jones platted Omaha City. On July 4, 1854, speculators from Council Bluffs celebrated the founding with a picnic on Capitol Hill, where Omaha Central High School stands today. By July 11, William P. Snowden’s log home was the first residence. Omaha incorporated as a city in 1857.
Omaha soon became the capital of Nebraska Territory. The first Territorial Legislature met there in January 1855, in a building the ferry company provided. However, rivals tried to move the capital almost every year. Omaha held it for thirteen years. Then Nebraska became a state on March 1, 1867, and the legislature moved the capital to Lincoln.
The Pacific Railway Act of 1862 created the Union Pacific Railroad. On November 17, 1863, President Lincoln issued an order that fixed the railroad’s eastern terminus on the Iowa side of the river, opposite Omaha. However, Union Pacific vice president Thomas Durant chose Omaha as the starting point. The company broke ground there on December 2, 1863.
A dispute followed. In 1875, the U.S. Supreme Court ruled in favor of Council Bluffs as the official terminus. Even so, Omaha became the railroad’s practical base, and Union Pacific has been headquartered there since its early years.
The first transcontinental railroad was completed in 1869. Three years later, in 1872, Union Pacific opened the first bridge across the Missouri River to Omaha. Before that, transfer boats carried trains across. As a result, trains could now run directly into the city, and warehouses and businesses grew along the rail corridors. By the 1880s, every major railroad in the country served Omaha.
The Union Stock Yards Company was organized in 1883. The yards received their first shipment, longhorn cattle from Wyoming, in August 1884. Livestock arrived by rail from ranches across the Great Plains. Over time, Omaha became one of the nation’s leading livestock markets, and by the mid-1950s its stockyards were the largest in the world. The stockyards closed in 1999.
South Omaha incorporated as a village in 1886 and grew around the stockyards and packing plants. Its population rose from more than 8,000 in 1890 to about 40,000 by 1915. Omaha annexed it on June 20, 1915.
The packing plants drew workers from around the world. Irish families came first, and Polish, Czech, Italian, Lithuanian, and Croatian immigrants followed. They built churches, businesses, and social clubs. Mexican families arrived in the early 1900s, some fleeing the Mexican Revolution. After packinghouses hired Mexican workers during a strike early in World War I, several hundred stayed. Today, South Omaha has a strong Mexican-American community.
In 1898, Omaha hosted a world’s fair. The Trans-Mississippi and International Exposition ran from June 1 until the fall. President William McKinley opened it by pressing a button in Washington. Over 2.6 million people came to see more than 4,000 exhibits. The Indian Congress brought more than 500 members of 35 Native nations. The fairgrounds were temporary, so no exposition buildings remain.
African Americans built a strong community in North Omaha. The Great Migration doubled Omaha’s Black population between 1910 and 1920. By the 1940s, the corner of 24th and Lake Streets was the heart of the Near North Side. The Dreamland Ballroom opened in 1922 and hosted stars like Count Basie and Louis Armstrong.
Black institutions flourished. Mildred Brown and her husband founded the Omaha Star on July 9, 1938, and it is still Nebraska’s only Black newspaper. Malcolm X was born in Omaha on May 19, 1925. Then, in 1947, the DePorres Club formed to fight segregation, and it organized boycotts and pickets.
However, the 1960s brought harm. The North Freeway demolished 753 homes and 25 businesses and split North Omaha in half. Today, the Great Plains Black History Museum at 2221 North 24th Street carries on this history. It marked its 50th anniversary in February 2026.
Omaha suffered severe racial violence during the Red Summer of 1919. On September 28, a mob of thousands stormed the Douglas County Courthouse and set it on fire. They seized Will Brown, a Black meatpacking worker, and lynched him. They also beat Mayor Edward P. Smith and nearly hanged him. Army troops restored order. The violence remains one of the darkest episodes in the city’s history.
On Easter Sunday, March 23, 1913, an F4 tornado struck Omaha. It killed an estimated 103 people and injured about 350. It damaged more than 3,000 buildings in the Omaha area. It remains the deadliest tornado in Nebraska history.
The Old Market, a red-brick National Register district, spans the area between 10th and 13th Streets and Farnam and Jackson Streets. It grew from Omaha’s historic warehouse and wholesale district. In 1989, the nearby Jobbers Canyon warehouse district was demolished, and ConAgra built its new campus there. Today, preservation efforts protect much of the Old Market’s architecture.
Union Station opened on January 15, 1931, and architect Gilbert Stanley Underwood designed it in the Art Deco style. It had thirteen tracks and served eight railroads. The last passenger train left in 1971. Union Pacific donated the building to the city in 1973, and in 1975 it opened as the Western Heritage Museum. It became the Durham Museum in 2008, and it is a National Historic Landmark. Today, the museum is open Tuesday through Sunday.
Offutt Air Force Base lies south of Omaha, next to Bellevue in Sarpy County. On November 9, 1948, Strategic Air Command moved its headquarters there from Andrews Air Force Base in Maryland. Military leaders chose it for its central location, far from the coasts. The U.S. Strategic Command replaced SAC on June 1, 1992. As a result, military activity became an important part of the wider Omaha economy.
Omaha kept growing after World War II. Neighborhoods like Dundee, Benson, Florence, and Millard joined the city through annexation. Between 2010 and 2020, Omaha’s land area grew from 127 to 142 square miles, and its population grew from 408,958 to 486,051.
The Census Bureau estimated Omaha’s population at 488,797 in July 2025. It is the 42nd-largest city in the United States and the largest in Nebraska. Omaha is the headquarters of four Fortune 500 companies: Berkshire Hathaway, Kiewit, Mutual of Omaha, and Union Pacific. John Ewing Jr. is the city’s mayor.
Omaha’s best-known businessman also changed roles. Warren Buffett announced in May 2025 that he would step down as CEO of Berkshire Hathaway. Greg Abel took over on January 1, 2026, and on September 18, 2026, Buffett stepped down as chairman. His son Howard became non-executive chairman.
The history of Omaha Nebraska runs from Indigenous homelands and a Missouri River ferry crossing to a major railroad, livestock, and business center. Speculators founded the city in 1854, and it served as territorial capital until 1867. Union Pacific broke ground there in 1863, and the stockyards drew immigrants from around the world. The city has also faced painful chapters, including the 1919 lynching and the North Freeway. Today, the Old Market, North 24th Street, and the Durham Museum preserve its story.
