Genghis Khan, the founder of the Mongol Empire, invaded and conquered large parts of present-day Afghanistan between 1219 and 1221 CE during his campaign against the Khwarazmian Empire. His forces entered the region after the execution of Mongol envoys by the Khwarazmian ruler, triggering a massive retaliatory invasion.
Major cities such as Balkh, Herat, and Ghazni were captured, many of them facing widespread destruction. The Mongol conquest reshaped the political structure of the region, leading to the سقوط of local powers and integration into the expanding Mongol Empire. Genghis Khan’s campaign left a lasting demographic and economic impact on Afghanistan, marking one of the most devastating invasions in its history.
