The Palmyrene Empire was a short-lived breakaway state from the Roman Empire resulting from the Crisis of the Third Century. Named after its capital city, Palmyra, it encompassed the Roman provinces of Syria Palaestina, Arabia Petraea, and Egypt, as well as large parts of Asia Minor.
The Palmyrene Empire was ruled by Queen Zenobia, officially as regent for her son Vaballathus, who inherited the throne in 267 at age ten. In 270, Zenobia rapidly conquered most of the Roman east, attempting to maintain relations with Rome as a legitimate power. In 271, she claimed the imperial title for both herself and her son, fighting a short war with the Roman emperor Aurelian, who conquered Palmyra and captured the self-proclaimed Empress. A year later the Palmyrenes rebelled, which led Aurelian to destroy Palmyra.
Despite its brief existence, the Palmyrene Empire is remembered for having been ruled by one of the most ambitious and powerful women in late antiquity. It is also hailed in Syria, where it plays an important role as an icon in Syrian nationalism.
