The February Revolution forced Nicholas II to abdicate; he and his family were imprisoned and later executed in Yekaterinburg during the Russian Civil War. The monarchy was replaced by a shaky coalition of political parties that declared itself the Provisional Government. On 1 September (14), 1917, upon a decree of the Provisional Government, the Russian Republic was proclaimed. On 6 January (19), 1918, the Russian Constituent Assembly declared Russia a democratic federal republic (thus ratifying the Provisional Government's decision). The next day the Constituent Assembly was dissolved by the All-Russian Central Executive Committee.
