Historical Context

1. Early Life and Rise to Power:

   • Born in Naissus (modern-day Niš, Serbia), Constantine was the son of Constantius Chlorus, a Roman general, and Helena, a Christian.

2. Conversion and the Battle of Milvian Bridge (312 CE):

   • Before the battle against Maxentius, Constantine reportedly saw a vision of a cross and the words In hoc signo vinces ("In this sign, you will conquer").

   • Following this vision, he adopted the Chi-Rho symbol (a Christogram) for his army, leading to victory.

3. Edict of Milan (313 CE):

   • Co-issued with Licinius, the edict granted religious tolerance throughout the empire, ending the persecution of Christians.

   • This decree allowed Christianity to flourish openly for the first time in Roman history.

   • The council produced the Nicene Creed, a foundational statement of Christian doctrine.

5. Founding of Constantinople (330 CE):

   • He relocated the Roman capital to Byzantium, renaming it Constantinople. This act positioned Christianity at the heart of imperial culture.
