Cirta - A settlement in Numidia
Cirta 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.
