for his strong-arm tactics. He had earlier crushed the rebellious Rajputs
  and he now murdered all the other members of the group of Forty. He then
  organised the defence against the Mongols, who were defeated by his son
  Muhammad in 1279 AD. He also killed a Turkish officer who, as sultan of
  Bengal, had declared his independence from Delhi. Balban’s descendants
  then ruled Bengal until 1338 AD, when Bengal once more became an
  independent state.
Internal Struggles The three decades after Iltutmish’s death were a time of
incessant struggle among the generals, governors, slaves and descendants of
the sultan. Iltutmish’s daughter Raziya ruled the realm for three years. The
contemporary chronicle Tabaqat-i-Nasiri describes her as a wise ruler and
competent military leader: “She had all the admirable qualities befitting a
ruler. But of what use were these qualities to her as fate had denied her the
favour of being born as a man?” She was deposed by the courtiers and when
she made an attempt to regain the throne with the help of one of them, she
was killed.
