Constantine the Great

Constantine I, also known as Constantine the Great, was a Roman emperor from AD 306 to 337. He was the first Roman emperor to believe in Christianity. Constantine was born in 272 in a place called Naissus, which is now Niš, Serbia. His father was Flavius Constantius, a Roman army officer, and his mother was Helena, a Greek woman. He served under emperors Diocletian and Galerius before becoming emperor in 306.

Constantine helped change how Christians were treated in Rome. In 313, he created the Edict of Milan. This allowed Christians to practice their religion freely. This made Christianity more accepted in the Roman Empire. He also started a new city called Constantinople, which is now Istanbul. This city became very important for many years.

Constantine made many changes to make the Roman Empire stronger. He changed the government and made a new gold coin called the solidus. He also helped build churches, like the Church of the Holy Sepulchre in Jerusalem. Constantine is remembered as an important leader who helped shape Roman history and the growth of Christianity.
