Zenobia: Queen of Palmyra and the Empire that Defied Rome explores the rise of one of antiquity's most formidable rulers during the crisis of the third century Roman Empire. From the desert city of Palmyra, Zenobia governed territories across the eastern Mediterranean, controlled major trade routes, and challenged Roman authority at a moment of invasion, instability, and weakened central rule. Her court stood at the meeting point of Roman, Greek, Aramaean, and eastern traditions. Drawing upon ancient literary accounts, archaeology, inscriptions, and coinage, this volume traces Palmyra's expansion, Zenobia's transition from regent to sovereign, the reach of her empire, and Rome's response under Emperor Aurelian. It also examines how Roman historians framed her authority and how later traditions transformed her into both rebel and romantic heroine. By placing Zenobia within the realities of imperial government, commerce, and regional power, the book reveals a ruler whose ambition was neither accidental nor symbolic, but politically calculated and historically significant. Part of the Powerful Female Rulers of Antiquity series, this volume examines a woman whose life shaped the political and cultural world of antiquity.
