Sultans of Delhi, Jalalat al-Din Radiyya, Gold Tanka, AH 635.

India, Sultans of Dehli, Jalalat al-Din Radiyya (AH 634-637 / 1236-1240 AD), Razia Sultan, Gold Tanka [Dinar], mint off flan [presumed Dehli], AH [6]35(?), AL-SULTAN, AL-A'ZAM, SHAMS AL-DUNYA WA'L DIN ILTUTMISH AL-SULTAN NASRAT AMIR AL-MU'MININ, rev FI AHAD AL-IMAM AL MUSTANSIR AMIR AL-MU'MININ, 11.03g (Goron & Goenka -; Hull - ). Not recorded in the major sources and believed to be unique. Of the very highest numismatic and historical importance.

Jalalat al-Din Radiyya, known as Razia Sultan, was the first female ruler of any Indian sultanate, the only woman elevated to the throne of Dehli and the only woman to have issued coins in the entire Sultanate series. Her father, Iltutmish, considered her so capable that he nominated her as his heir saying, "My sons are devoted to the pleasures of youth, and no one of them is qualified to be king. They are unfit to rule the country, and after my death you will find that there is no one more competent to guide the State than my daughter". Nevertheless, she faced dissent from high ranking officials opposed to the concept of a woman leading the sultanate and, on the death of her father, Dehli was besieged by a hard-line rebel alliance who nominated Razia's elder brother as ruler. After a short period of conflict, however, two prominent members of that rebellion defected at which point the others fled and Razia took her place as Sultan. She refused to be addressed as Sultana - implying wife or consort or daughter of the sultan - ruling instead as Sultan in her own right. To gain respect from those traditionalists who doubted her she discarded the veil, wore a man's head-dress and rode an elephant at the head of her armies but despite her resolve, throughout her short reign she repeatedly faced rebellion and was ultimately abandoned by her troops, on campaign, captured, killed and decapitated in Kaithal.

Her first coins followed the style of her father's but crucially include the title Nasrat, the feminine form of Nasir, to identify them as her own. One other gold coin of Razia Sultan is recorded. It is of Bengali style and listed by Goron & Goenka as B55. The present coin is in the style of Iltutmish's Dehli issues, cf Goron & Goenka D30, and is believed to be unique - as is Razia Sultan in the history of India.
