The District of Bamako has been divided into six communes (distinguished by numbers, and not named) since Ordinance No. 78-34/CNLM of 18 August 1978, and amended by a law in February 1982 establishing the new boundaries of Communes III and IV. Each commune is administered by the municipal council and a mayor elected from among its members. The last elections were held on 26 April 2009 and the Alliance for Democracy in Mali hold the majority of representatives for the communes.
