The <entity_0> by the Mongol Empire under the leadership of Genghis Khan occurred in what is now the town of <entity_2> in <entity_1>. The <entity_3> occurred while the Mongols were pursuing Jalal ad-Din Mingburnu, the last ruler of the Khwarezmian Empire, and his newly raised forces in <entity_1>. This death, compounded by the heavy casualties sustained by his forces during the <entity_3> and the realization of his own mortality, angered Genghis to the extent that once he captured <entity_2> he completely destroyed it and massacred the population of the city and its surrounding region.
