The dissolution of the Ottoman Empire (1908–1922) was a period of history of the Ottoman Empire beginning with the Young Turk Revolution and ultimately ending with the empire's dissolution and the founding of the modern state of Turkey.
The Young Turk Revolution restored the constitution of 1876 and brought in multi-party politics with a two-stage electoral system for the Ottoman parliament. At the same time, a nascent movement called Ottomanism was promoted in an attempt to maintain the unity of the Empire, emphasising a collective Ottoman nationalism regardless of religion or ethnicity. Within the empire, the new constitution was initially seen positively, as an opportunity to modernize state institutions and resolve inter-communal tensions between different ethnic groups.
