This edict granted freedom of worship to all religions within the Roman Empire, including Christianity. It ended years of persecution and marked the beginning of a new era of religious tolerance.

4. Political Involvement: Constantine played an active role in the internal affairs of the Church. He convened the Council of Nicaea in 325 CE, which formulated the Nicene Creed, a statement of Christian beliefs that remains central to the faith to this day.
5. Conversion: Constantine's personal conversion to Christianity had a significant influence on the Empire and the Church. His conversion symbolized the shift from a predominantly pagan society to a Christian one, shaping the religious landscape of Europe for centuries to come.
6. Administrative Reforms: Constantine's administrative reforms, such as the division of the empire into dioceses and provinces, helped to strengthen the Church's organization and governance.
7. Legal Status of Christians: Constantine's reign saw a significant improvement in the legal status of Christians. They gained equal rights with other citizens and were allowed to hold public office, further integrating them into Roman society.
