USA, 1865–1975 – The Era of Reconstruction and the Gilded Age, 1865–1890:…

The idea

The period 1865–1890 witnessed unprecedented US economic growth, driven by the rise of powerful corporations and monopolies. Railways were the engine of this expansion, creating a national market, stimulating heavy industry, and enabling westward migration. The oil industry, dominated by figures like John D. Rockefeller and his Standard Oil corporation, pioneered horizontal integration and trust-building. Concurrently, developments in agriculture, such as mechanisation and the opening of the Great Plains, vastly increased production but led to falling prices and agrarian discontent. This industrial and agricultural boom fuelled rapid urbanisation, as millions of immigrants and rural Americans flocked to expanding cities to provide the cheap labour necessary for corporate dominance.

What earns the marks

• Explain the role of railways in driving economic growth by creating national markets and stimulating demand for coal and steel.
• Analyse the rise of corporations and trusts, using the oil industry and Standard Oil as a primary example of monopolistic practices.
• Evaluate developments in agriculture, noting how mechanisation increased yields but caused overproduction and economic hardship for small farmers.
• Assess the causes and impacts of urbanisation, linking industrial expansion to the rapid growth of city populations and changing labour demographics.

Common mistakes and how to put them right

• Viewing agricultural developments as purely positive.

  Put it right: Recognise that while overall production increased, mechanisation and overproduction led to falling prices and severe debt for many farmers.

• Treating the rise of corporations in isolation.

  Put it right: Explicitly link corporate growth to the expansion of the railway network, which provided both the infrastructure and the business model for large-scale enterprises.

• Assuming urbanisation was solely driven by immigration.

  Put it right: Include the significant internal migration of rural Americans moving to cities in search of industrial employment.

Exam tips

• Use specific business strategies, such as horizontal and vertical integration, to explain how corporations in the oil and railway sectors achieved dominance.
• Link developments in agriculture directly to the railways, as farmers became entirely dependent on train networks to transport their goods to urban markets.
• When evaluating economic growth, contrast the immense wealth generated by corporations with the challenging living conditions created by rapid, unregulated urbanisation.
