Which emperor initiated the policy of tolerating or promoting Christianity and moved the capital toward the east?

• A. Constantine the Great
• B. Theodosius I
• C. Marcus Aurelius
• D. Julius Caesar

Answer: (A)

Constantine the Great marks a turning point when the Roman state began openly embracing Christianity and shifting political power toward the eastern provinces. The Edict of Milan in 313 granted religious tolerance to Christians, ending the persecutions and giving them legal status across the empire. But his support went beyond tolerance: he backed Christian leaders, funded church-building, and presented himself as a Christian emperor, which helped Christianity gain legitimacy and influence at the highest levels of governance.

At the same time, Constantine moved the capital from Rome to Byzantium, renaming the city Constantinople in 330. This relocation created a new political and logistical center in the eastern half of the empire, aligning imperial power with the more prosperous and densely populated eastern provinces and shifting strategic focus to the East.

Theodosius I later codified Christianity as the state religion, but the initial policy of toleration and promotion, along with the capital shift, originates with Constantine.
