Mohammad Yaqub Khan (1849 – November 15, 1923) was Emir of Afghanistan from February 21 to October 12, 1879.
He is the son of the previous ruler, Sher Ali Khan.
Mohammad Yaqub Khan is the governor of Herat province in Afghanistan and decides to rebel against his father in 1870 but is imprisoned in 1874.
The Second Anglo-Afghan War erupts in 1878, leading Sher Ali Khan to flee the capital of Afghanistan, and eventually die in February 1879 in the north of the country.
As Sher Ali's successor, Yaqub signs the Treaty of Gandamak with the British in May 1879, relinquishing control of Afghanistan foreign affairs to the British Empire.
An uprising against this agreement led by Ayub Khan in October of the same year ends forces the abdicateion of Yaqub Khan.
