The river served as Columbus's connection to the world, particularly enabling it to ship its commodity cotton crops from the plantations to the international cotton market via New Orleans and ultimately Liverpool, England. The city's commercial importance increased in the 1850s with the arrival of the railroad. In addition, textile mills were developed along the river, bringing industry to an area reliant upon agriculture. By 1860, the city was one of the more important industrial centers of the South, earning it the nickname "the Lowell of the South", referring to an important textile mill town in Massachusetts.
