Genghis Khan launched a multi-pronged invasion of the Khwarazmian Empire, besieging the border town of Otrar. A large Mongol force under Genghis and his son Tolui then drove southward into Transoxiana. Genghis isolated Samarkand by first capturing and destroying Bukhara in a surprise manoeuvre, then ravaging nearby towns and repelling relief forces.
In March 1220, the Mongol army, reinforced after taking Otrar, ambushed and massacred a defending sortie outside Samarkand. The city's Muslim clergy persuaded citizens to surrender. Most survivors were enslaved or conscripted. A small garrison held the citadel for about a month before roughly half broke through Mongol lines and escaped across the Amu Darya.
After the fall, Samarkand was comprehensively looted and pillaged, effectively ending its role as the Khwarazmian capital. Over time the city recovered under the Pax Mongolica and later rose again as the capital of the Timurid Empire in the late fourteenth century, demonstrating a gradual but significant urban revival following the destruction.
