Alger (department)

The departments created on this date were the civil zone of the three provinces corresponding to the beyliks of the Regency of Algiers recently conquered.

Considered as a French province, Algeria was departmentalised on 9 December 1848, thereby operating according to the same administrative structure as metropolitan France.

The département of Alger covered an area of 54,861 km2 (21,182 sq mi), and comprised six sub-prefectures: these were Aumale, Blida, Médéa, Miliana, Orléansville and Tizi-Ouzou.

Until 10 January 1957, when the Sahara regions received their own administrative structure, these territories were administered by the département of Alger.

The 1957 departmental reorganisation was marked by a change in the "suffix" number appearing on automobile license plates and in other places that used the same code.
