1914 Ottoman jihad proclamation

On 11 November 1914, Ottoman Caliph Mehmed V proclaimed holy war against the Entente powers and appealed for support from Muslims in Entente-controlled countries. The declaration, which called for Muslims to support the Ottomans in Entente-controlled areas and for jihad against "all enemies of the Ottoman Empire, except the Central Powers", was initially presented on 11 November and published in Takvim-i Vekayi the following day.
