The Industrial Revolution in America: How a Farm Nation Became a Factory

In 1800, the United States was an agricultural country where about ninety-four percent of the population lived in rural areas and most families produced most of what they consumed. By 1900, it was the largest industrial economy in the world, having surpassed Britain in the 1880s. The transformation took a single century and remade almost everything — the landscape, the workforce, the social structure, and the country's position in the world.

Several factors converged to make American industrialization so rapid. The country had extraordinary natural resources: coal in Pennsylvania and West Virginia, iron ore around the Great Lakes, timber across vast swaths of the continent, and rivers to power early mills. It had a growing population fed partly by massive immigration from Europe, providing industrial labour. It had a legal system that protected private property and enforced contracts. And it had a political culture that, whatever its other contradictions, celebrated individual commercial ambition with relatively few aristocratic or guild-based restrictions.

The railroads were central to everything. The first transcontinental railroad was completed in 1869 with the driving of the golden spike at Promontory Summit in Utah. Within decades, rail lines stitched together a continental market, moving raw materials to factories and finished goods to consumers at a scale that had been physically impossible before. The railroads created their own demand for steel, coal, and machinery, stimulating the industries that then served them. They also created the first large-scale American corporations and the first experiments in modern management and accounting.

The steel industry, anchored by Andrew Carnegie's operations in Pittsburgh, illustrated the logic of American industrialization. Carnegie relentlessly adopted new technology, drove down costs, integrated his operations vertically from raw materials to finished product, and undercut his competitors on price while still making enormous profits. When J.P. Morgan bought Carnegie Steel in 1901 and merged it into U.S. Steel, the transaction created the first billion-dollar corporation in American history.

The human cost of all this was substantial. Industrial workers labored long hours in dangerous conditions for wages that were modest by any comparison to the fortunes being assembled at the top. Child labor was common. Workplace accidents were frequent and inadequately compensated. The gap between the Gilded Age's spectacular wealthy and its working poor was as wide as anywhere in the industrializing world.

And yet productivity kept growing, real wages did rise over the long run, and the goods produced by American industry became progressively cheaper and more widely available. The internal combustion engine, the telephone, the electric light — the period from roughly 1870 to 1914 generated a cascade of innovations that reshaped daily life. America was building the material foundation for the century that would belong to it.
