Young Turk Revolution

The Young Turk Revolution (July 1908; Turkish: Jön Türk Devrimi) was a constitutionalist revolution in the Ottoman Empire. Revolutionaries belonging to the Internal Committee of Union and Progress (CUP), an organization of the Young Turks movement, forced Sultan Abdul Hamid II to restore the Constitution, recall the parliament, and schedule an election. Thus began the Second Constitutional Era which lasted from 1908–1912 and also the Turkish Revolution, an era of political instability and social change which lasted for more than four decades.

The revolution took place in Ottoman Rumeli in the context of the Macedonian Struggle and the increasing instability of the Hamidian regime. It began with CUP member Ahmed Niyazi's flight into the Albanian highlands. He was soon joined by İsmail Enver, Eyub Sabri, and other Unionist officers. They networked with local Albanians and utilized their connections within the Salonica based Third Army to instigate a large revolt. A string of assassinations by Unionist Fedai also contributed to Abdul Hamid's capitulation. Though the constitutional regime established after the revolution eventually succumbed to Unionist dictatorship by 1913, the Ottoman sultanate ceased to be the base of power in Turkey after 1908.

Immediately after the revolution, Bulgaria declared independence from the Ottoman Empire and Austria-Hungary's annexation of nominal Ottoman territory sparked the Bosnian Crisis.

After an attempted monarchist uprising known as the 31 March incident in favor of Abdul Hamid the following year, he was deposed and his half-brother Mehmed V ascended the throne.
