Mohammadzai (Pashto: محمدزی‎), also spelled Moḥammadzay (meaning "descendants of Mohammad"), 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 1823 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.
