The Hazaras have long been the subject of persecution in Afghanistan, including enslavement during the 19th century and ethnic and religious persecution for hundreds of years. In the 20th and 21st centuries, they have also been the victims of massacres committed by the Taliban and al-Qaeda. Hazaras have been systemically killed and discriminated against socially, economically, and culturally with specific intent, argued by some to constitute genocide. The Hazaras primarily come from the central regions of Afghanistan, known as Hazarajat. Significant communities of Hazara people also live in Quetta, Pakistan and in Mashad, Iran, as part of the Hazara and Afghan diasporas.
During the reign of Amir Abdur Rahman (1880–1901), millions of Hazaras were massacred, expelled, and displaced. Half the population of Hazarajat was killed or fled to neighboring regions of Balochistan in British India and Khorasan in Iran. This led to Pashtuns and other ethnic groups occupying parts of Hazarajat.
