The State Duma is the lower chamber of the Federal Assembly, serving as the primary legislative body of the Russian Federation. Composed of 450 elected deputies, its mandate includes introducing and passing federal legislation, approving the appointment of the Prime Minister, and exercising oversight over the executive branch. Established under the 1993 Constitution following the dissolution of the Soviet-era Supreme Soviet, it revived the historical name of the imperial legislative assemblies first convened in 1906.
