Lesson 4: Industry and Corporations

Key Idea

After the Civil War, new inventions transformed American industry. The Bessemer process was a new method for making steel much stronger and cheaper than before. This breakthrough allowed factories to produce massive quantities of high-quality steel for the first time.

This affordable steel became the backbone of a growing nation. It was used to build thousands of miles of railroad tracks, long bridges, and the frames for the first skyscrapers. The huge demand for steel created a powerful new industry and set the stage for the rise of industrial giants.

Key Idea

After the Civil War, building giant businesses like railroads and steel mills required more money than one person could provide. The corporation emerged as a new way to fund these huge projects. A corporation could raise vast sums of money by selling small pieces of ownership, called stock, to many different people.

This structure allowed companies to grow to an unprecedented size. With this power, business leaders could create monopolies or trusts — powerful groups of companies that worked together to control an entire industry, set prices, and eliminate competition.

Key Idea

To fund massive projects, many businesses became corporations. A corporation is a business that sells shares of ownership, called stock, to investors. These investors, known as stockholders, owned a piece of the company and shared in its profits, allowing businesses to raise huge amounts of money.

This new structure allowed powerful bankers to shape American industry. Financiers like J.P. Morgan arranged huge loans and helped merge smaller companies into giant corporations. By financing and combining businesses, these bankers gained immense influence over the economy.

Key Idea

Powerful business leaders aimed to eliminate competition and control entire industries. One method was horizontal integration, where a company buys out its competitors. An oil company, for example, could purchase other oil refineries to dominate the market.

Another strategy was vertical integration. This involved owning all the different businesses on which a company depended for its operation. A steel producer might buy coal mines, iron ore fields, and the railroads needed to transport materials, controlling every step of production.
