Thanks for asking the question.
The first and only women to rule the throne of Delhi was Razia Sultan. She was the daughter of the Muslim emperor Shams ud din Iltutmish. She was a member of the Mamluk dynasty and she ruled for a short duration of four years only. Her reign was cut short due to her death.
