 The Rise of U.S. Hegemony: Origins, Evolution, and Impact

Introduction

U.S. hegemony refers to the political, economic, military, and cultural dominance exerted by the United States over global affairs. While the U.S. emerged as a powerful state in the 19th century, its hegemony was firmly established after World War II. The country leveraged its economic strength, military capabilities, and ideological influence to shape global institutions, trade systems, and security frameworks.

This essay examines the origins of U.S. hegemony, tracing its evolution from the early 20th century to the present. It analyzes the mechanisms through which the U.S. established dominance, including economic policies, military alliances, cultural influence, and geopolitical strategies. The discussion also explores challenges to U.S. hegemony and the prospects of a shifting global order.

1. Early Foundations of U.S. Power (1776–1918)

1.1 Emergence of the U.S. as a Regional Power

The United States gained independence from Britain in 1776 and spent the 19th century consolidating its national identity and expanding its territorial and economic base. Key developments included:

The Spanish-American War marked the U.S.'s entry into global politics:

The U.S. defeated Spain and gained control over Puerto Rico, Guam, and the Philippines.

The war established the U.S. as a naval power with strategic overseas territories.

The Platt Amendment (1901) allowed U.S. intervention in Cuba, reinforcing its influence in Latin America.

1.3 Economic and Industrial Growth
