İttihadism was a prominent Nationalist ideology in the Ottoman Empire, that came about after the Young Turk Revolution of 1908. Whilst the Revolution resulted in Educution reform, the Secularization of Ottoman society and the expansion of women's rights, it also led to the rise of Turkish Nationalism, that culminated in the Armenian Genocide of 1915-1917. It was the official ideology of the Committee of Union and Progress.

Nationalism
The leadership of the Committee of Union and Progress (CUP) was always Nationalist, but they didn't stress it until the Balkan Wars of 1912-1913, so not to worry the non-Turkish population of the Ottoman Empire. A big problem for the CUP was that the majority of Turks inhabiting the Ottoman Empire didn't see themselves as Turkish, but as Sunni Muslims who spoke the Turkish Language.
