The Young Turk Revolution (July 1908) of the Ottoman Empire took place when the Young Turk movement forced Sultan Abdulhamid II to restore the Ottoman constitution of 1876 and ushered in multi-party politics within the Empire. From the Young Turk Revolution to the Empire's end marks the Second Constitutional Era of the Ottoman Empire's history. More than three decades earlier, in 1876, constitutional monarchy had been established under Abdulhamid during a period of time known as the First Constitutional Era, which lasted for only two years before Abdulhamid suspended it and restored autocratic powers to himself.
