The history of the Medea region takes its roots in the distant past. During the Roman domination, several cities were built among which Lambdia. The ruins of Rapidum (Djouab) and Thanarusuma (Berrouaghia) attest to this Roman presence. In the Xth century, with the advent of the Fatimids, Ziri chief of the Sanhadjas tribes, founded the kingdom of the Zirides, he built his capital at Achir (near Ain Boucif). And authorized his son Bologhine to create three other cities: Al-Djazair, Miliana and Médéa.
