Cirta was repopulated by Romans by the founder of what Roman empire?
Cirta Cirta (from Berber: KRTN or Kirthan, Phoenician: "Tzirta" ) was the capital city of the Berber Kingdom of Numidia in northern Africa (modern Algeria). Its strategically important port city was Russicada. Although Numidia was a key ally of the ancient Roman Republic during the Punic Wars (264–146 BC), Cirta was subject to Roman invasions during the 1st and 2nd centuries BC. Eventually it went under Roman dominion during the rule of Julius Caesar. Cirta was then repopulated by Roman colonists by Caesar and Augustus and was surrounded by a "Confederation of free Roman cities" (Tiddis, Cuicul, Milevum, etc.) The city was destroyed in the beginning of the 4th century and was rebuilt by the Roman emperor Constantine the Great, who gave his name to the newly constructed city, Constantine. Vandals damaged Cirta, but emperor Justinianus I reconquered and improved the Roman city. Arabs finally captured it in 698 AD.
Constantine the Great Constantine the Great (Latin: "Flavius Valerius Aurelius Constantinus Augustus" ; Greek: Κωνσταντῖνος ὁ Μέγας ; 27 February 272 AD – 22 May 337 AD), also known as Constantine I or Saint Constantine (in the Orthodox Church as Saint Constantine the Great, Equal-to-the-Apostles), was a Roman Emperor of Illyrian-Greek origin from 306 to 337 AD. He was the son of Flavius Valerius Constantius, a Roman Army officer, and his consort Helena. 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. In 305, Constantius raised himself to the rank of "Augustus", senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Constantine was acclaimed as emperor by the army at Eboracum (modern-day York) after his father's death in 306 AD, and he emerged victorious in a series of civil wars against Emperors Maxentius and Licinius to become sole ruler of both west and east by 324 AD.
