American Imperialism in the Late 19th Century: Causes and Consequences
This essay examines the principal forces driving American overseas expansion in the late 19th century, focusing on economic ambition and nationalist ideology. It traces the influence of Alfred T. Mahan's naval theory, the concept of Manifest Destiny, and Senator Albert Beveridge's imperialist arguments. The paper surveys key consequences of American expansionism — including the acquisition of Cuba, Puerto Rico, and the Philippines following the Spanish-American War — and discusses domestic opposition through the Anti-Imperialist League. It concludes by connecting late 19th-century imperialism to subsequent U.S. interventions in China, the brokering of the Russo-Japanese War peace, the construction of the Panama Canal, and ultimately the conflict with Japan in World War II.

What makes this paper effective
- It efficiently integrates primary sources — Beveridge's Senate speech and the Anti-Imperialist League's Platform — to give competing ideological voices on expansion direct representation.
- The paper traces a clear causal chain from Mahan's naval theory through Manifest Destiny to concrete geopolitical outcomes, giving the argument a logical through-line.
- By ending with World War II, the essay demonstrates long-range historical consequences, showing how early policy decisions reverberate across decades.
Key academic technique demonstrated
The paper uses direct quotation from primary sources to substantiate ideological claims rather than simply asserting them. By quoting both proponents (Beveridge) and opponents (the Anti-Imperialist League, Lincoln) of imperialism, the author lets historical actors speak for themselves, grounding analytical assertions in original evidence and demonstrating the tension between expansionist and anti-expansionist camps.
Structure breakdown
The essay opens with a thesis identifying economic and nationalist motivations, then elaborates each in turn through Mahan, Perry, and Beveridge. A central section surveys the territorial results of the Spanish-American War, followed by a paragraph on domestic opposition. The final section traces downstream consequences — China, the Russo-Japanese War, the Panama Canal, and World War II — giving the paper a satisfying arc from causes to long-term effects.
Introduction: Roots of American Overseas Expansion
There were two main reasons for American overseas expansion in the late 19th century: economic and nationalistic motivations. As America entered the industrial revolution, it sought to expand commercially, which meant securing overseas materials and markets. Alfred T. Mahan explained this concept in his 1890 book The Influence of Sea Power upon History, arguing that modern industrial nations need foreign markets for their goods and must maintain a naval force capable of protecting those markets. As the United States began to industrialize its navy, it also cultivated a strong sense of nationalism.
Beginning with the concept of "Manifest Destiny" — the belief that God had granted Americans the entire continent to settle and civilize — by the late 1800s Americans had expanded this idea beyond the shores of the Pacific Ocean. Rather than simply conquering new territory, Americans framed their actions as introducing liberty and freedom to peoples around the world. This became the justification for the opening of Japan in the 1850s, the Spanish-American War, American intervention in China, American intervention in Latin America, and it continues to serve as justification for American intervention around the world today.
Economic Motives and the Role of Sea Power
Senator Albert J. Beveridge, in his speech "In Support of an American Empire," spelled out a practical rationale for the American occupation of the Philippines. He stated that "our largest trade must be with Asia… The Philippines give us a base at the door of all the East" (Beveridge). Increased trade with Asia had been an American aspiration since the early days of the Republic, and had been significantly advanced by the 1852 visit of Commodore Perry to Japan. The opening of Japan ensured supply bases for American ships sailing to that part of the world and, in turn, increased the volume of American shipping in the region.
Nationalist Ideology and the 'Civilizing Mission'
In addition to expanded trade, the American people developed a sense of obligation to "civilize" what they considered the uncivilized parts of the world. Senator Beveridge echoed this idea in his speech, asserting that God "has marked the American people as his chosen nation to finally lead in the regeneration of the world. This is the divine mission of America, and it holds for us all the profit, all the glory, all the happiness possible to man" (Beveridge).
