The Council of District Dumas (Russian: Совет районных дум, romanized: Sovet rayonnykh dum, abbreviated SRD) was an institution which, following the October Revolution, functioned from October 1917 to March 1918 as the city government of Moscow. During its tumultuous existence, the Council of District Dumas attempted to revive the municipal governance of the city, but struggled with financial difficulties and a protracted strike movement by city administration employees. The Council and its executive were chaired by the Bolshevik leader Mikhail Vladimirsky.
