Yemen Vilayet

Yemen Vilayet is a first-level administrative division (vilayet) of the Ottoman Empire.

At the beginning of the 20th century it reportedly has an area of 200,000 square kilometers (77,200 sq mi).

The population for the vilayet is given by the 1885 Ottoman census as 2,500,000.

Broadly speaking, the vilayet is 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 is demarcated by the Anglo-Turkish Boundary Commission of 1902–1905, while the limit of the eastern border is left vague.
