By the time of Sultan Barquq, the first Circassian (or Burji) Mamluk Sultan, in the late 14th century, Egypt had been significantly affected by the ravages of the Black Death but continued to be the center of great economic activity, with many commercial and religious buildings still being constructed at this time. During Barquq's first reign (1382-1389) his Master of the Stables ("amir akhur"), Jaharkas al-Khalili, demolished the Fatimid mausoleum (the Turbat az-Za'faraan) to erect a large khan at the heart of the city, which became known as Khan al-Khalili. The name later came to denote the entire district. Jaharkas reportedly disposed of the bones of the Fatimid royal family by throwing them into the rubbish hills east of the city.
