SteamboatsSteamboats are ships powered by steam, which propels the rotation of large paddle wheels that move the vessel through water. Steamboats were a vital element of the U.S. transportation system from their invention in the late eighteenth century until the late nineteenth century. Because steamboats generate their own consistent source of power, typically generated through the burning of coal, and could operate in shallow waters, they had an unprecedented ability to navigate rivers and other inland waterways, and were particularly valuable for traveling upriver and against currents that other vessels could not surmount. Steamboats were also used in the deep coastal waters along the eastern seaboard of the United States. Their use for the transport of people and goods was central to the development of the U.S. economy after independence and before the proliferation of rail lines in the late 1800s.
The first workable steamboat was demonstrated by John Fitch (1743–98) in 1787 on the Delaware River. Although he built several steamboats and received a patent for his design in 1791, Fitch struggled to demonstrate the commercial viability of his technology and lost the support of his backers. However, the impetus to create steam-powered vessels was not dead. Among many who sought to improve upon Fitch's start were John Stevens and Robert Fulton, who both built and operated steamboats in the early nineteenth century. From these origins, steamboats proliferated.
By 1817 dozens of steamboats were in operation on the Mississippi and Ohio rivers and their tributaries. By 1840 there were more than 200 on the Mississippi alone, and by 1860 this number had swelled to more than 1,000. Mississippi steamboat traffic and trade pushed New Orleans to exceed New York City in volume of shipping by 1850, with New Orleans' outbound cargo accounting for more than half of the nation's total exports. Steamboat technology was put to use on many kinds of vessels, but packets that carried passengers and cargo from city to city were the most common kind; these vessels made settlement possible by permitting travel from West Virginia in the East to the Rocky Mountains in the West, and from Minnesota in the North to Louisiana in the South.
