 Before Shaykh died in 1421, he sought to offset the power of the Circassian mamluks by importing Turkish mamluks and installing a Turk as "atabeg al-asakir" in 1420 to serve as regent for his infant son Ahmad.However, following his death, a Circassian emir, Tatar, married Shaykh's widow, ousted the "atabeg al-asakir" and assumed power.Tatar died three months into his reign and was succeeded by Barsbay, another Circassian emir of Barquq, in 1422.
