Transcaucasian Commissariat
In 1912, when Fourth Duma of Russian Empire convened in Saint Petersburg, Mammad Yusif Jafarov was elected by the Muslim population of Baku, Ganja and Erivan governorates to represent them in state parliament. In Saint Petersburg, he joined Constitutional Democratic Party (also known as "Kadets"). While in the Duma, he repeatedly criticized Tsar's government for their unjust colonization policy in Azerbaijan. On March 9, immediately after Russia's February Revolution, the interim government established the Transcaucasian Committee of the Duma. Jafarov was one of the members of the committee that managed the industrial and economic operations. On November 15, 1917, he was appointed Commissar of Industry and Trade of Transcaucasian Commissariat.
