Before Constantine rose to power as the Roman emperor, the empire followed polytheistic beliefs. Any deviation from this tradition, particularly embracing Christianity, was met with severe punishment including imprisonment, torture, and execution. Christians were especially targeted as their faith was considered a "cult" at the time. However, after Constantine embraced Christianity, there was a significant shift. In 325 CE, Constantine summoned early Christian leaders to Nicaea (modern-day ?znik in Turkey) to deliberate on matters pertaining to the governance and doctrines of a unified Christian church This gathering aimed to establish a single, cohesive, and catholic church that would unify the Roman world under one dominant religion.
