Power. Ambition. Betrayal. This historical spectacle, produced by Croatian Radiotelevision, explores the life of Diocletian—a Roman emperor whose legacy left an indelible mark on this region. Set against the turbulent backdrop of the 3rd century, the film follows Diocletian’s journey: from a young officer from Salona to the Roman emperor who saved the Empire from collapse, only to lose what mattered most. Through two interwoven timelines—his rise to power and the final year of his reign, marked by the Great Persecution of Christians—a complex tale unfolds, touching upon power, ambition, love, betrayal, and the heavy price of authority. This visually lavish historical spectacle blends a political thriller with an intimate human drama, offering an epic reconstruction of one of the most pivotal eras in Roman history. It culminates in a revelation that reshapes the legacy of an emperor whose name remains inextricably linked to the city of Split and Diocletian’s Palace to this day.
