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. ‎
