Pax Americana

Pax Americana (Latin for "American Peace", modeled after Pax Britannica and Pax Romana) is a term applied to the concept of relative peace in the Western Hemisphere and later the world as a result of the preponderance of power enjoyed by the United States beginning around the middle of the 20th century and continuing to this day. 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, and regionally in the Americas at the start of the 20th century.
