In the 10th century, Kurds joined the persecution of Yazidis in the Hakkari mountains after having Islamized.[6] Muslim Kurds persecuted the Yazidis with particular brutality.[7] Muslim Kurds attacked Yazidis due to religion.[8][9] Sometimes, during these massacres, Muslim Kurds tried to force the Yazidis to convert to Islam.[10][11] Almost the whole Yazidi population were nearly wiped out by massacres carried out by Turks and Kurds in the 19th century.[12][13]
