The 31 March Incident (, , , or ) was a political crisis within the Ottoman Empire in 1909, during the Second Constitutional Era. Occurring soon after the 1908 Young Turk Revolution, in which the Committee of Union and Progress (CUP) had successfully restored the 1876 constitution and ended the absolute rule of Sultan Abdul Hamid II, it was in part a reactionary response by Islamists opposed to the secularising influence of the CUP and supporters of absolutism.
