Cairo, Illinois, once occupied one of the most strategically important locations in the interior United States, standing at the confluence of the Ohio and Mississippi rivers. Founded in 1837 by Darius Holbrook of Boston through the Cairo City & Canal Company, the site was still rough and swampy in its early years; Charles Dickens famously described it as a “dismal swamp” in 1842. To make the town viable, bonds were sold to finance levees against annual flooding and to drain the surrounding lowlands for development.
Cairo later grew into a major transportation and commercial center. Its economy was built on river traffic, rail connections, and ferry operations, and in 1854, Congress designated it a port of delivery. A federal Custom House and Post Office followed in 1869. By the late nineteenth century, Cairo had become a critical transfer point where as many as 500,000 railroad cars a year were ferried across the Ohio and Mississippi rivers. In 1886, the value of shipments moving by river and rail reached $60 million, reportedly the highest per capita total in the nation.
That importance began to erode with the construction of permanent crossings. The Illinois Central Railroad Bridge over the Ohio River, completed in 1899, sharply reduced the need for railcar ferries. A second railroad bridge at Thebes across the Mississippi further weakened that trade. Automobile bridges completed across the Mississippi in 1929 and the Ohio in 1937 finished the process, collapsing the ferry business and undermining the industries tied to it.
Another shift came in the mid-twentieth century, when diesel-powered towboats replaced coal-fired steamboats. As steam traffic declined, the fueling docks, repair shops, and related riverfront facilities that had supported it also disappeared. Cairo’s population peaked at about 15,000 in 1920 and remained relatively stable for several decades, but the city entered a prolonged decline as its transportation-based economy contracted.
That decline deepened amid decades of racial conflict and violence. By the mid-twentieth century and after, Cairo was marked by bombings, lynchings, and sustained unrest, and the city began losing population at a dramatic rate. It has never recovered its former prominence.
Looked like Berlin after World War II when I visited. I was told that most of the white business owners left en masse rather than integrate their businesses.
Thanks for your report. I was born in Cairo in 1955 in the house at 1334 Commercial St. I do remember the uprising in the 1960’s. I had six brothers that took part of said. This came from the hanging of their friend (sic) Junebug in the city jail. Again, thankfully for bring Cairo to attention of the Americans. ” A City That will never be forgotten.”
Just drove through Cairo last week and was seeking some kind of historical economic development reason for the city to have become commercially obsolete. I was guessing tax advantages in Indiana, Kentucky, or Missouri had pulled most businesses away. But the changing modes of transportation that you describe here as well as the disappearance of the Union/Confederate border tells most of the story.
Cairo, IL plays a big part in Neil Gaiman’s excellent book, “American Gods.” Hopefully, the Showtime adaptation (in which Gillian Anderson was just cast) will be half as good as the book.
