 Between 1885 and 1888, the Pashtun population in northern Afghanistan might have increased eightfold–from 3,500 Pashtun families in 1885 to 40,000 Pashtun families in 1888.Rebellions such as the Ghilzai Pashtuns' rebellions in eastern Afghanistan and Sardar Muhammad Ishaq's rebellion temporarily stopped Pashtun colonization of northern Afghanistan in the late 1880s.Afterwards, despite another short period of colonization, the Hazara War broke out in the early 1890s, ending the Pashtunization of northern Afghanistan during Abdur Rahman’s reign (1880–1901) (though it would resume under Abdur Rahman's successors after his death).
