Muzaffari'd-Dín became the shah of Persia. He was the son of Násiri'd-Dín Sháh. He had been sent as governor to the province of Azerbaijan in 1861 and, as the crown prince, had spent 35 years in the pursuit of pleasure. When he ascended to the throne he was unprepared for the office. In addition, the country had huge debts to both Britain and Russia.
After an almost bloodless revolution Muzaffari'd-Din Sháh was forced to sign a document calling for a National Assembly to be elected from amount the working guilds, landowners merchants and the nobles. The parliament was opened on the 7th of October. [AY24]
