Constantine the Great, originally known as Flavius Valerius Constantinus, divorced his first wife, Minervina, in a calculated move to marry Fausta, the daughter of Maximian, who had recently retired from the imperial throne. This marriage took place against the backdrop of the Tetrarchy, a system of rule in the Roman Empire established by Diocletian, which divided the empire among four rulers to improve governance amidst various crises. By marrying Fausta, Constantine was not just forging a personal bond but also strengthening his political alliances, as Maximian's family wielded significant influence.

The union with Fausta was emblematic of a shifting political landscape, where dynastic marriages played a crucial role in consolidating power. This matrimonial alliance aimed to bring together separate factions and stabilize the western provinces of the empire, where Constantine sought to assert his authority following the chaotic end of the Tetrarchy. The marriage also signaled a transition for Constantine from being a local ruler in Gaul to becoming a more prominent player on the imperial stage.

Beyond political motives, the marriage had social implications as well, as it positioned Constantine more favorably among the elite of the time. His connection to Maximian's family secured a degree of legitimacy. However, the complexities of their personal lives and the political intrigue that ensued set the stage for a tumultuous reign marked by both internal strife and expanding territories. As the Roman Empire faced challenges from external and internal forces, such alliances became increasingly vital for maintaining power and influence throughout the realm.
