For the duration of control by Imperial Russia, Estonia was divided between two governorates. The Governorate of Estonia in the north corresponded roughly to the area of Danish Estonia and the northern portion of Governorate of Livonia, which had a majority of ethnic Estonians. These two areas were amalgamated on by administrative reforms of the Russian Provisional Government. Elections for a provisional parliament, Maapäev was organized, with the Menshevik and Bolshevik factions of the Russian Social Democratic Labour Party taking a share of the vote. On 5 November 1917, two days before the October Revolution in Saint Petersburg, Estonian Bolshevik leader Jaan Anvelt led his leftist political forces in an anti-democratic coup in Tallinn, attempting to usurp political power in governorate from governor Jaan Poska on 9 November. On the Maapäev, refusing to recognize the attempted Bolshevik coup d'état, proclaimed itself to be the only legally elected and constituted authority in Estonia. However, it was soon driven underground by the Bolsheviks. During the reign of the Soviet Estonian Executive Committee, Ants Dauman, the newly elected mayor of Narva, organized a plebiscite with an intention of removing the towns of Narva and Ivangorod from the Petrograd Governorate and adding them to the new autonomous governorate, receiving permission for the referendum on from the All-Russian Central Executive Committee. As 80% of the town's population supported the joining in the plebiscite, the Soviet Estonian Executive Committee recognized the new additions to the governorate on. Even though this had happened under the Bolshevik regime, the later Estonian government acknowledged the referendum, and the addition of Narva and Ivangorod to Estonia. In February, after the collapse of the peace talks between Soviet Russia and the German Empire, mainland Estonia was occupied by the Germans. Bolshevik forces retreated to Russia. On 23 February 1918, one day before German forces entered Tallinn, the Salvation Committee of the Estonian National CouncilMaapäev emerged from underground and issued the Estonian Declaration of Independence. Although it took nearly 9 months for Estonia to be liberated from German occupation and Red Army, the day after that date is still celebrated as Estonia's independence day.
