Question

these two rulars were slaves of qutb-uddin aibak​

Answer 1

Answer:

Iltutmish was succeeded by his family members, and then by his slave Ghiyas ud din Balban. This line of kings is called Mamluk or Slave dynasty; however, this term is a misnomer. Only Aibak, Iltutmish, and Balban were slaves, and seem to have been manumitted before their ascension to the throne.
