Constantine the Great, born in 272 AD as Flavius Valerius Constantinus, was a transformative figure in Roman history. Ascending to the purple in 306 AD, he marked the onset of a new era for the Roman Empire. Constantine's most significant contribution was his role in the conversion of the Roman Empire to Christianity. In 313 AD, he issued the Edict of Milan, a groundbreaking decree that granted religious tolerance to Christians, effectively ending the centuries-long persecution they had endured.

Constantine's reign was characterized by notable military achievements and administrative reforms. He won critical battles, including the famous Battle of Milvian Bridge in 312 AD, where he claimed to have seen a vision of the Christian Chi-Rho symbol, interpreted as a divine omen of victory. In 324 AD, he emerged victorious over his rival Licinius, solidifying his sole rule over the Roman Empire. His administrative changes featured the establishment of Constantinople (modern-day Istanbul) as the new eastern capital, ultimately becoming the epicenter of the Byzantine Empire. Constantine's conversion to Christianity had a profound and enduring impact on Western history, shaping the course of the Roman Empire and the development of Christianity in the Western world. His legacy as the first Christian Roman Emperor and his role in fostering Christian doctrine at the First Council of Nicaea in 325 AD left an indelible mark on the religious and political landscape of the time.
