Dissolution of the Ottoman Empire
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.
