Pax

Pax is a Latin noun meaning peace. In historiography, it is used as a label for extended periods of relative peace attributed to the dominance of a particular power over a region or the world order. Notable examples include Pax Romana, a term describing relative peace in the Roman Empire; Pax Britannica, referring to British maritime supremacy and stability in the 19th century; Pax Americana, describing post-World War II American influence; and Pax Mongolica, the era of stability and commerce across Eurasia under Mongol rule.

In modern usage, Pax appears as a given name. The most widely known bearer in popular culture is Pax Jolie-Pitt, the son of actors Angelina Jolie and Brad Pitt. The title Pax has also appeared in literature, notably the novel Pax by Sara Pennypacker, about a boy and his fox, and as a stand-alone title for other works.

PAX is also the brand name of a major set of gaming conventions, originally standing for Penny Arcade Expo. PAX events are organized by ReedPop and feature video games, tabletop games, cosplay, and industry panels. The flagship PAX Prime/West is held in Seattle, with PAX East in Boston, PAX South in San Antonio, and PAX Australia in Melbourne, among other local events.
