Iltutmish had organized a group of forty loyal Turkish nobles known as the 'Turkan-i-Chahalgani' or 'Group of Forty'. Over time, this group became very powerful and acted as kingmakers. Ghiyasuddin Balban, who rose from being a member of this group to becoming the Sultan of Delhi, systematically broke the power and influence of the Chahalgani nobles to strengthen the authority of the monarch.
