Yemen Vilayet (Ottoman Turkish: ولايت یمن Vilâyet-i Yemen; Turkish: Yemen Vilayeti) was a vilayet of the Ottoman Empire. At the beginning of the 20th century it reportedly had an area of 77,200 square miles (200,000 km2). The population for the vilayet is given by the 1885 Ottoman census as 2,500,000, an unreasonably high number for this barren land of deserts which would have been more than the whole population of the far more fertile Ottoman Mesopotamia.
Broadly speaking, the vilayet was bounded by the 20th parallel north to the north, the Aden protectorate to the south, the Red Sea to the west and the 45th meridian east to the east. The southern border was demarcated by the Anglo-Turkish Boundary Commission of 1902-1905, while the limit of the eastern border was left vague.
The vilayet was established in 1872.
In the 1830s, aided by the collapse of the Zaidi Imamate due to internal division and the adoption of modern weaponry after the Crimean War, the Ottomans moved into northern Yemen, eventually taking San'a and making it the capital of the Yemen Vilayet in 1872. Even then, Ottoman control was largely confined to cities, and the Zaidi imam's rule over Upper Yemen was formally recognized.
Starting in 1872, after the Sana'a region was firmly under control, Ahmed Muhtar Pasha set about restructuring the administration of the Yemen vilayet, dividing it into four sanjaks, with San'a' city serving as capital of the vilayet. Asir became a sanjak of Yemen in 1872.
In the late 19th century, the Zaidis rebelled against the Turks, and Imam Mohammed ibn Yahya laid the foundation of a hereditary dynasty. When he died in 1904, his successor Imam Yahya ibn Mohammed led the revolt against the Turks in 1904-1905, and forced them to grand important concessions to the Zaidis. The Ottoman accepted to withdraw the civil code and restore sharia in Yemen.
Izzat Pasha concluded a treaty with Imam Yahya in October 1911, by which he was recognised as temporal and spiritual head of the Zaidis, was given the right to appoint officials over them, and collect taxes from them. The Ottomans maintained their system of government in the Sunni-majority parts of Yemen.
In March 1914, the Anglo-Turkish Treaty delimited the border between Yemen and the Aden Protectorate. When World War I broke out, Imam Yahya remained nominally loyal to the Sultan, but tried to negotiate with Britain at the same time. The Asir, on the other hand, joined Britain as soon as the war began. The Arab Revolt in Hejaz cut off Yemen from the rest of the Ottoman Empire, and the imam took the opportunity to establish his power over all of Yemen.
Turkish forces withdrew in 1918, and Imam Yahya strengthened his control over northern Yemen creating the Mutawakkilite Kingdom of Yemen.
