Sioux City was laid out in 1854 by Dr. John K. Cook, sent by the United States Federal Government to survey northwestern Iowa, who was impressed by the location at the mouths of the Big Sioux and Floyd Rivers at the Missouri. Within 3 years it had a population of 400 people and incorporated as a city.
Steamboat traffic first arrived at Sioux City in 1865, and the railroad arrived in 1868.
In 1885 the city had a population of some 20,000. That decade the city had a building boom, and an elevated railroad and early "skyscrapers" were built. President Grover Cleveland visited in 1887.
In 1915 the Industrial Workers of the World staged free speech demonstrations which resulted in mass arrests, filling the city's jails to overflowing. Further major strikes shut down the city in 1921 and 1922, most notably protesting conditions in the packing house industry.
In 1932 and 1933 a farmers strike occupied the city for some time, preventing food shipments in protest of very low agricultural prices.
