Amir al-Mumenin al-Mutawakkil 'Ala Allah Rab ul-Alamin Imam Yahya bin al-Mansur Bi'llah Muhammad Hamidaddin.
Coinage [AH 1322-1367 (1904-1948)]
 
Religious leaders of the Zaydi sect of Shia Islam expelled forces of the Ottoman Empire from what is now northern Yemen by the middle of the 17th century but, within a century, the unity of Yemen was fractured due to the difficulty of governing Yemen's mountainous terrain. In 1849, the Ottoman Empire occupied the coastal Tihamah region to put pressure on the Zaiddiyah imam to sign a treaty recognizing Ottoman suzerainty and allowing for a small Ottoman force to be stationed in Sana'a. However, the Ottomans were slow to gain control over Yemen and never managed to eliminate all resistance from local Zaydis. In 1913, shortly before World War I, the Ottoman Empire was forced to cede some power formally to highland Zaydis. On 30 October 1918, following the collapse of the Ottoman Empire, Imam Yahya Muhammad of the al-Qasimi dynasty declared northern Yemen an independent sovereign state. In 1926, Yahya proclaimed the Mutawakkilite Kingdom of Yemen, becoming both a temporal king as well as a (Zaydi) spiritual leader, and won international recognition for his new state, such as with the Kingdom of Italy, entering into the Italo-Yemeni Treaty in 1926.
In the 1920s, Yahya had expanded his power to the north into Tihamah and 'Asir, but he collided with the rising influence of the Saudi king of Nejd and Hejaz, Abdul Aziz ibn Sa'ud. In the early 1930s, Saudi forces retook much of these gains before withdrawing from some of the area, including the southern Tihamah city of Al Hudaydah. The present-day boundary with Saudi Arabia was established by the 20 May 1934 Treaty of Taif, following the Saudi-Yemeni War in 1934. Yahya's non-recognition of his kingdom's southern boundary with the British Aden Protectorate (later the People's Democratic Republic of Yemen) that had been negotiated by his Ottoman predecessors resulted in occasional clashes with the British.
The Kingdom of Yemen became a founding member of the Arab League in 1945 and joined the United Nations on 30 September 1947. It committed a small expeditionary force to the 1948 Arab–Israeli War. Imam Yahya was assassinated in an unsuccessful coup d'état in 1948, but was eventually succeeded by a firm heir - Yahya's son, Imam Ahmad bin Yahya, who regained power several months later.
