On 21 July 1905 , members of the Armenian Revolutionary Federation attempted to assassinate Abdul Hamid II by placing a horse carriage bomb in front of the mosque , an event known as the Yıldız assassination attempt . Although the bomb failed to kill the sultan due to an unforeseen delay , it killed 26 others and wounded 58 more . The attempt was in response to the pogroms and massacres against Armenians and other minorities of the Ottoman Empire carried out by Abdul Hamid II 's government , the Hamidian massacres
