How long has American Imperialism been going on?

Answer 1

American Imperialism has roots that trace back to the late 19th century, particularly around the 1890s, with events such as the Spanish-American War in 1898 marking a significant expansion of U.S. influence overseas. This period saw the acquisition of territories like Puerto Rico, Guam, and the Philippines. While the term "imperialism" often evokes this era, aspects of American expansionism can be identified even earlier, with the westward expansion and Manifest Destiny in the 19th century. Today, discussions of American imperialism continue, reflecting ongoing debates about U.S. foreign policy and military presence worldwide.
