Young Turks (Turkish: Jön Türkler, from French: Les Jeunes Turcs) was a political reform movement in the early 20th century that consisted of Ottoman exiles, students, civil servants, and army officers. They favoured the replacement of the Ottoman Empire's absolute monarchy with a constitutional government. Later, their leaders led a rebellion against the absolute rule of Sultan Abdul Hamid II in the 1908 Young Turk Revolution. With this revolution, the Young Turks helped to establish the Second Constitutional Era in 1908, ushering in an era of multi-party democracy for the first time in the country’s history.
After 1908, the Young Turks’ initial umbrella political party, the Committee of Union and Progress (CUP; Turkish: İttihat ve Terakki Cemiyeti), began a series of modernizing military and political reforms across the Ottoman Empire. However, the CUP soon began to splinter as many of the more liberal and pro-decentralization Young Turks left to form an opposition party in late 1911, the Freedom and Accord Party (also known as the Liberal Union or Liberal Entente), with much of those staying in the CUP favoring a generally nationalist and pro-centralization policy. In a year-long power struggle throughout 1912, Freedom and Accord and the remaining members of the CUP vied for control of the Ottoman government, the year seeing a rigged election by the CUP and a military revolt by Freedom and Accord.
