Arte broadcast a documentary today detailing the life and reforms of Constantine the Great and his impact on the Roman Empire [2].

The film examines a pivotal transition in Western history, exploring how Constantine shifted the empire from a divided state toward a unified, Christian-influenced power. This period defined the religious and political landscape of Europe for centuries.

The documentary, titled “Constantin le Grand, l’empereur de la nouvelle Rome,” visits key historical sites across the former Roman Empire [2]. It focuses on the fourth century [1], a time of significant instability and reform. The narrative traces the emperor's rise to power and his efforts to consolidate authority over a fractured territory [3].

Central to the film is the discussion of the tetrarchy, a system of government where power was shared among four rulers [4]. The program explores how Constantine navigated this complex political structure, as well as the influence of his father, Constantius Chlorus [3]. By revisiting the physical locations associated with these events, the production provides a geographic context to the administrative changes of the era.

Beyond political unification, the documentary highlights the opening of the way to the empire's Christianization [2]. It analyzes the reforms that allowed Christianity to move from a persecuted sect to a dominant institutional force. These shifts are presented as the foundation for the “New Rome,” marking a departure from the traditional Roman pagan order [3].

The program aired on Saturday, May 30, 2026 [2]. According to the broadcaster's digital distribution, the content will remain available until Aug. 28, 2026 [4].

“Constantine shifted the empire from a divided state toward a unified, Christian-influenced power.”

The focus on Constantine's unification of the empire and his religious reforms underscores the transition from classical antiquity to the early Middle Ages. By highlighting the shift from the tetrarchy to a single ruler and the adoption of Christianity, the documentary contextualizes the birth of the Byzantine Empire and the institutionalization of the church in state governance.
