The sixth period of American history (1877-1917) witnessed a whirlwind of transformation and turmoil that profoundly shaped the nation’s identity and trajectory. From the rise of industrial giants to the emergence of social movements and the expansion of an empire, this era was a crucible that forged the modern United States.

Industrialization and Economic Expansion
The Industrial Revolution hit the United States like a thunderbolt, propelling the nation towards unparalleled economic growth. Inventions such as the Bessemer process and the telephone revolutionized industries, while the growth of railroads and telegraphs connected the country like never before. By 1900, the United States had become the world’s leading industrial power.

- Steel production: Rose from 385,000 tons in 1877 to 46 million tons in 1917
Social Transformation
The Industrial Revolution brought about profound social changes, creating new opportunities and challenges for Americans. Urban populations swelled as people flocked to cities for factory jobs, leading to overcrowding and social tension. Immigration surged, with millions of Europeans seeking a better life in America.
Key Figures:
- Urban population: Increased from 3.3 million in 1870 to 30.1 million in 1900
- Immigration: Over 25 million immigrants arrived between 1880 and 1920
Political and Social Movements
Social upheavals sparked political and social movements aimed at addressing the inequalities and injustices of the time. The Progressive Era (1890s-1920s) saw the rise of labor unions, women’s suffrage activists, and reformers fighting for social justice.

Imperialism and Expansion
The late 19th century witnessed a surge in American imperialism, driven by a desire for economic expansion and national prestige. The United States acquired colonies in the Pacific (Hawaii, Guam) and the Caribbean (Puerto Rico, Cuba), while also intervening in Latin America.
Key Events:
- Spanish-American War (1898): Resulted in the acquisition of Puerto Rico, Guam, and the Philippines
- Roosevelt Corollary to the Monroe Doctrine (1904): Gave the United States the right to intervene in Latin America to prevent European influence
Foreign Policy and World War I
American foreign policy in the early 20th century focused on economic expansion and maintaining global stability. President Woodrow Wilson’s “New Freedom” agenda emphasized free trade and anti-trust legislation. The United States eventually entered World War I in 1917 after the sinking of the Lusitania.
Key Figures:
