The Estonian Provincial Assembly (Estonian: Maapäev) was elected after the February Revolution in 1917 as the national diet of the Autonomous Governorate of Estonia in Russian Empire. On November 28, 1917, after the October Revolution the Assembly declared itself the sovereign power on Estonia and called for the elections of the Estonian Constituent Assembly. On the eve of the German occupation of Estonia in World War I the council elected the Estonian Salvation Committee and issued the Estonian Declaration of Independence on February 24, 1918.
On April 12, 1917 the Russian Provisional Government issued an order on the provisional autonomy of Estonia. The Governorate of Estonia, comprising what is now northern Estonia was merged with the Estophone northern part of the Governorate of Livonia, to form the autonomous governorate. The Russian Provisional Government decreed that a provincial assembly, colloquially known as the Maapäev, be created with members elected by indirect universal suffrage.
Elections for the 62 deputies of the diet were held in many stages; members representing the rural communities were elected in two-tiered elections in May-June, while the town representatives were elected in July-August, 1917. The election process saw the creation and reorganization of Estonian national parties.
