Europe, north africa and eastern asia wide peace was achieved under pax romanis.
World peace was achieved,
pretty much, under pax britannica in the nineteenth century. However, world peace was only achieved because every
government in the world was
•Part of the
british empire
• Vichy Government acting on behalf of London (China, most of africa not under the empire and parts of europe)
•Too afraid of Britains' reaction to actually start a war, fearing they would be replaced by a vichy government or raided by the rest of the empire.
