Among the several causes of the insurrection, four are prominent in retrospect:
1. Discontent of different groups; especially, those who lost their jobs, because of the new regime. As Abdülhamid II’s spy network collapsed after the revolution, hundreds of people earning their living from activities of espionage lost their income. The same was valid for those who benefited from the nepotism of the old regime. Hundreds of civil servants who did not have the qualifications for the positions they occupied but only loyal to the sultan, lost their jobs.
2. In the army, there was a friction between the alaylı officers, who had risen through ranks and favored by the old regime, and the mektepli officers, who had been trained in military schools and the military academies. The latter were the driving force behind the 1908 revolution. Most of the alaylı officers lost their status after the revolution and the system of promotion from the ranks ended. It was this friction in the army that inflamed the insurrection.
3. The constitutional regime brought about a change of atmosphere, the secularization of social life which threatened the position of the lower ulema. A particular discontent arose among the students of theology whose right of exemption from military service was made conditional to a certain degree of success in exams made by the ministry of war. Students who failed to pass the threshold level were to be recruited to military service.
4. The discontent of the opposition party. The Party of Ottoman Liberals viewed the Unionist policies as irresponsible and disliked their attempt to monopolize power. This resentment was a significant factor in creating the circumstances favorable for the break out of the insurrection.
