In August 1906, an Ottoman Delegation arrived to the Imam, expressing the desire to re-open negotiations, to which the Imam reportedly responded with by stating his desire to end the bloodshed.[1] Five years of negotiations ensued, and ended with the signing of the Treaty of Daan on 9 October 1911, which led to Yemen becoming a vassal state of the Ottoman Empire. It was effective for 7 years, until the Imam of Yemen capitalized on the Ottoman collapse in World War I and created the Mutawakkilite Kingdom of Yemen on 30 October 1918.[6]
