In 1908, after the Young Turk Revolution, he began publishing the newspaper "Tanin", which became a strong supporter of the ruling party, the Committee of Union and Progress ("Ittihat ve Terakki Cemiyeti", CUP). He was eventually disappointed with their politics, and returned to Galatasaray High School as the principal; however, during the anti-CUP reactionary 31 March Incident ("31 Mart Vakası") of 1909, he chained himself to the school gates as a protest and resigned the same day.
