Who was Constantine?Constantine the Great (27 February 272 AD-22 May 337 AD) was a Roman Emperor who ruled between 306 and 337 AD. Born on the territory now known as Nis, located in Serbia, he was the son of Flavius Valerius Constantius, a Roman Army officer of Illyrian origins. His mother Helena was Greek. His father became Caesar, the deputy emperor in the west, in 293 AD. Constantine was sent east, where he rose through the ranks to become a military tribune under Emperors Diocletian and Galerius. Constantine was the first Roman emperor to convert to Christianity. Although he lived most of his life as a pagan, he joined the Christian faith on his deathbed, being baptised by Eusebius of Nicomedia. He played an influential role in the proclamation of the Edict of Milan in 313, which declared religious tolerance for Christianity in the Roman empire. He called the First Council of Nicaea in 325 AD that produced the statement of Christian belief known as the Nicene Creed.
Where is Rome?Rome is the capital city of Italy and a special comune (named Comune di Roma Capitale). Rome also serves as the capital of the Lazio region. With 2,872,800 residents in 1,285 km2 (496.1 sq mi), it is also the country's most populated comune. It is the fourth-most populous city in the European Union by population within city limits. It is the centre of the Metropolitan City of Rome, which has a population of 4.3 million residents. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber. The Vatican City is an independent country inside the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states. Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe.
