Shajar al-Durr
Both the Ayyubids in Syria and the Abbasid Caliph al-Musta'sim in Baghdad defied the Mamluk move in Egypt and refused to recognize Shajar al-Durr as a Sultana but the Mamluks in Egypt renewed their oath to the new Sultana, and she appointed Aybak to the important position of Atabeg (commander in chief).
