As a part of the 2011 Kallikratis government reform, the regional unit East Attica was created out of the former prefecture East Attica (Greek, Modern (1453-);: νομαρχία Ανατολικής Αττικής). The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.[1]
