Ethnic groups in Afghanistan
The Hazara is the third largest ethnic group in Afghanistan. They are Persian-speaking and reside mainly in the Hazarajat region in central Afghanistan. The Hazaras seem to have partial Turco-Mongol origins with admixture from surrounding indigenous, Iranian-speaking groups. Linguistically the Hazara speak a dialect of Persian, known as Hazaragi, and sometimes their variant is interspersed with Turkic and Mongolic words. It is commonly believed that the Hazara are descendants of Genghis Khan's army, which invaded Afghanistan during the 12th century. Proponents of this view hold that many of the Mongol soldiers and their family members settled in the area and remained there after the Mongol empire dissolved in the 13th century, converting to Islam and adopting local customs. Most of the Hazaras practice Shia Islam, while most of the other Afghans are Sunni. They are between 6 to 7 million. 
Some notable Hazaras of Afghanistan include: Abdul Ali Mazari, Ismael Balkhi, Karim Khalili, Sultan Ali Keshtmand, Habiba Sarābi, Sarwar Danish, Ustad Muhammad Akbari, Sima Samar, Ramazan Bashardost, Abdul Haq Shafaq, Sayed Anwar Rahmati, Qurban Ali Urozgani, Azra Jafari, Ahmad Shah Ramazan, Muhammad Mohaqiq, Ahmad Behzad, Nasrullah Sadiqi Zada Nili, Rohullah Nikpai, Hamid Rahimi, Fariba Rezayee, Wakil Hussain Allahdad and Dawood Sarkhosh.
