Ali bin Hamud of Zanzibar

Sayyid Ali bin Hamud al-Busaidi (7 June 1884 – 20 December 1918; علي بن حمود البوسعيد), also known as Ali II, was the eighth Sultan of Zanzibar from 1902 to 1911.

Biography
Hamud was proclaimed Sultan of Zanzibar on 20 July 1902, following the death of his father, the seventh Sultan, two days earlier. There was a regency until he attained majority.

He served only a few years as sultan because of illness. On 9 December 1911 he abdicated in favour of his brother-in-law Khalifa bin Harub Al-Busaid.

During his reign slavery in Zanzibar was fully abolished with the abolition of concubinage in 1909.
