What Was the Second Industrial Revolution? How Electricity Created Mass Production
Electric power, cheap steel, and the moving assembly line turned factories into engines of mass production.
The Second Industrial Revolution is usually dated from about 1870 to the start of World War I. Where the first revolution ran on steam, this one added electricity, steel, chemicals, and oil, and it reorganized the factory itself around speed, standard parts, and repeatable processes.
What technologies defined it?
Electric power and electric motors, cheap steel from processes such as the Bessemer method, the telegraph and telephone, the internal combustion engine, and a growing chemical industry. Together they made energy more flexible, materials stronger, and communication much faster.
How did electricity change the factory?
Steam factories used one central engine and a web of overhead shafts and belts, so machines had to sit close together. Electric motors let each machine have its own power source. Layouts could follow the logic of the work, not the position of the shaft. Many factories took years to exploit this fully.
What is the assembly line's role?
Interchangeable parts and divided tasks already existed, but Henry Ford's moving assembly line, introduced at Highland Park in 1913, brought them together. Commonly cited figures say Model T chassis assembly fell from over twelve hours to roughly an hour and a half, which made cars affordable to many more buyers.
What is scientific management?
Frederick Winslow Taylor argued that work could be studied, timed, and standardized to raise efficiency. His ideas shaped how factories planned tasks and measured output. They also drew criticism for treating workers like parts of a machine, a debate that still echoes in discussions of work design.
What changed for ordinary people?
Mass production lowered prices for goods such as clothing, tools, and vehicles. Cities grew, electric lighting spread, and new jobs appeared in factories and offices. At the same time, repetitive work and tight supervision became common, which fueled organized labor and workplace regulation.
How did electricity reach factories?
Early power stations, such as Thomas Edison's Pearl Street Station in New York in 1882, supplied direct current to nearby customers. Alternating current systems, promoted by Westinghouse and Tesla, could carry power over longer distances and won out for large grids. Factories gradually switched from private steam engines to purchased electricity.
Which industries grew fastest?
Steel, electrical equipment, chemicals, petroleum, and automobiles all expanded quickly, along with the railways and shipping that moved their products. Large corporations became common because these industries needed heavy investment. That shift toward big business is one of the era's lasting economic legacies.
How did communication change?
The telegraph, which spread widely from the 1840s, and the telephone, patented in 1876, let companies coordinate suppliers, factories, and customers across long distances. Faster information supported national markets and large corporations. In effect, communication networks became part of industrial infrastructure alongside railways and power lines.
What was Fordism?
Fordism refers to Ford's combination of standardized products, assembly-line production, and relatively high wages, including the five-dollar day announced in 1914. The idea was that well-paid workers could also become customers. It influenced factory organization worldwide, although later producers moved toward more flexible, varied output.
Why is it called the second revolution?
Historians use the label to mark a change of energy and organization: from steam, iron, and textiles toward electricity, steel, and chemicals. Some prefer terms such as technological revolution, and the boundary with the first revolution is blurry. The number is a convenient shorthand, not a precise date stamp.
The takeaway
The Second Industrial Revolution turned manufacturing into mass production. Electricity made energy flexible, steel made structures stronger, and the assembly line made output fast and repeatable. It lowered prices and reshaped daily life, while also making work more standardized and tightly managed.
