Ottoman territory began to fracture long before the empire collapsed entirely. In the 19th century independence movements began to flourish. Several Ottoman territories became independent, including Greece, Romania, and Serbia. Other territories gained a significant level of autonomy, such as Egypt under Muḥammad ʿAlī and Bulgaria. By the 20th century the empire saw a number of other movements that also sought self-determination. Turkish nationalism, Arab nationalism, and Armenian nationalism were among the most prominent.

Economic Difficulties

The economy of the Ottoman Empire suffered significantly after European powers began trading with East Asia and the East Indies by sea rather than through Ottoman-controlled land routes. As revenues declined, the empire responded in part by increasing taxes or resorting to confiscations, which only worsened the situation. The empire accrued enormous debt by the mid-19th century. The problem was exacerbated in the 1870s by drought, flooding, and a global financial crisis.

Reforms and Resistance

Ottoman sultans attempted to rescue the empire through a series of reforms intended to modernize the state. The most important of these were the Tanzimat reforms, introduced between 1839 and 1876. The sultans increasingly centralized control of the state as reforms were made in the areas of finance, administration, justice, education, and the military. However, as all legal authority became concentrated in the hands of the sultans, resistance arose, particularly among a group of dissidents known as the Young Turks.

Young Turk Revolution

Spearheaded by college students and discontented military officers, the Young Turks led a revolution against the authoritarian regime of sultan Abdülhamid II. The group succeeded in 1908 in forcing Abdülhamid to restore the 1876 constitution. The Young Turks deposed the sultan the following year. After their rise to power, the group promoted a new spirit of Turkish nationalism.

World War I

The empire did not initially have significant interest in the outcome of World War I. The Young Turk government largely preferred to stay neutral. But after Germany appeared poised for victory in the early months of the war, opportunists in the government, such as Enver Paşa, believed that supporting the German war effort would be beneficial to the ailing empire. The Allied powers ultimately prevailed over the Central Powers, however. The Treaty of Sèvres, the postwar settlement between the Allies and the Ottomans, greatly reduced Ottoman territory.

The Rise of Atatürk

A new government under the leadership of Mustafa Kemal, who later became known as Atatürk, emerged at Ankara, Turkey. The last Ottoman sultan, Mehmed VI, fled to Malta in 1922 after the sultanate had been abolished. In 1923 Turkey was proclaimed a republic. Atatürk served as its first president. All members of the Ottoman dynasty were subsequently expelled from the country. [How well do you understand the rise and fall of the Ottoman Empire?
