Pax Americana

Pax Americana[1][2][3] (Latin for "American Peace", modeled after Pax Romana, Pax Britannica, and Pax Mongolica) is a term applied to the concept of relative peace in the Western Hemisphere and later the world beginning around the middle of the 20th century, thought to be caused by the preponderance of power enjoyed by the United States.[4] Although the term finds its primary utility in the latter half of the 20th century, it has been used with different meanings and eras, such as the post-Civil War era in North America,[5] and regionally in the Americas at the start of the 20th century. https://en.wikipedia.org/wiki/Pax_Americana

Pax Americana is primarily used in its modern connotations to refer to the peace among great powers established after the end of World War II in 1945, also called the Long Peace. In this modern sense, it has come to indicate the military and economic position of the United States in relation to other nations. For example, the Marshall Plan, which spent $13 billion to rebuild the economy of Western Europe, has been seen as "the launching of the pax americana".[6]

The Latin term is modeled after the Roman Empire's Pax Romana. The term Pax Americana is most notably contraposed to the Pax Britannica (1815–1914) under the British Empire, which served as global hegemon and constabulary from the late 18th century until the early 20th century.[7]
