Siege of Baghdad (1401)

In 1401, Timur besieged Baghdad for forty days and then massacred its inhabitants for resisting.

[1] The Mongol army looted the treasury and razed much of the city, except for mosques and madrasas.

[2] Contemporaries reported that each Mongol soldier was ordered to bring at least one severed head of an inhabitant.

Only one out of a hundred of the city's inhabitants reportedly survived the massacre to be sold into slavery.
