The New Empire by Walter LaFeber is a historical analysis of the United States’ emergence as an imperial and global power, particularly from the late 19th century through the 20th century. It examines how economic interests, political ideology, and strategic concerns drove American expansion beyond its borders, especially in Latin America and the Pacific. The book focuses on key events such as the Spanish-American War and the growth of U.S. influence in global markets, arguing that economic motivations were central to the development of American foreign policy and its transformation into a modern empire.
