مظفر الدين شاه
In 1906 during the drafting of the first Persian Constitution, a bicameral parliament was agreed upon in order to obtain royal approval from Mozaffar ad-Din Shah Qajar. The shah was to appoint half of the 60 members of the upper house, the Senate. The other half of the Senate was to be elected by a two-stage process. The shah expected to be able to control legislation by influencing the Senate. Mozaffar ad-Din Shah Qajar signed the Constitution at the end of December 1906 but died unexpectedly of a heart attack a few days later. Radical politicians and other constitutional delegates did not want a Senate, and after the shah died no action was taken to form one. In mid-1907, the Anjumans of the Mujahidin, a group of workers, artisans and peasants, called for much wider voting rights for men, and they expressed a wish that the Senate never be formed because it would make the nobility more powerful.
