Mohammadzai (Pashto: محمد زی), also spelled "Moḥammadzay" (meaning sons of Mohammad in Pashto language) is a sub-tribe or clan of the Barakzai which is part of the Durrani confederacy of tribes. They are primarily centered on Kandahar, Kabul and Ghazni in Afghanistan. The Mohammadzai ruled Afghanistan from 1826 to 1978, for a total 152 years. The monarchy ended under Mohammad Zahir Shah when his brother in law Sardar Daoud Khan took power via a coup.
Mohammadzai are the most prominent and powerful branch of the Durrani confederacy, and are primarily centered on Kandahar. They can also be found in other provinces throughout Afghanistan as well as across the border in Pashtunistan.
Musahiban are the descendants of Sultan Mohammad Khan also known as "Telai". Telai means Gold in Dari. He was the elder brother of Dost Mohammed Khan. The Musahiban are closely related to King Amanullah.
Barakzai Mohammadzai's usually have the southern dialect of Pashto, however many Mohammadzai's speak Dari as a first (or second language), especially those whom live around Persian speaking non-Pashtun Afghans.
