longest period of peace in europe
Europe During the Long Peace, 1871-1914. The longest period of uninterrupted peace in Europe since the height of the Roman Empire. In a sense, we've already managed to exceed it by many years (1945-1999 v. 1871-1914), but this is illusory. Major confrontations affecting Europe have occurred in faraway places, especially the Middle East and Asia.
Pax Romana (Latin for Roman Peace) was the long period of relative peacefulness and minimal expansion by the Roman military force experienced by the Roman Empire after the end of the Final War of the Roman Republic and before the beginning of the Crisis of the Third Century.
