Razia Sultan:-
The fifth Sultana was Razia-al-Din, who had the titular name of Razia Sultana and reigned from 1236 to 1240. As the first female Muslim ruler in Inda, she initial managed to impress the nobles and administratively handled the Sultanate well. However, she began associating with the African Jamal-ud-Din Yaqut, provoking racial antagonism amongst the nobles and clergy, who were primarily Central Asian Turkic and already resented the rule of a female monarch. She was defeated by the powerful nobleman Malik Altunia whom she agreed to marry. Her half-brother Muiz-ud-din Bahram, however, usurped the throne with the help of the Chihalgani and defeated the combined forces of the Sultana and her husband. The couple fled and reached Kaithal, where their remaining forces abandoned them. They both fell into the hands of Jats and were robbed and killed on 14 October 1240.
Muiz-ud-din Bahram:-
The sixth Sultan was Muiz-ud-din Bahram, who had the titular name of Sultan and reigned from 1240 to 15 May 1242. During his reign, the Chihalgani became disorderly and constantly bickered among each other. It was during this period of unrest that the Mongols invaded the Punjab and sacked Lahore. Muiz-ud-din Bahram was too weak to take any action against them, and the Chihalgani besiged him in the White Fort of Delhi and put him to death in 1242.
Ala-ud-din Masud:-
The seventh Sultan was Ala-ud-din Masud, who had the titular name of Sultan and reigned from 1242 to 1246. He was effectively a puppet for the Chihalgani and did not actually have much power or influence in the government. Instead, he became infamous for his fondness of entertainment and wine. By 1246, the chiefs had become upset with Ala-ud-din Masud's increasing hunger for more power and replaced him with his cousin Nasir-ud-din Mahmud, who was another grandson of Iltutmish.
Nasir-ud-din Mahmud:-
The eighth Sultan was Nasir-ud-din Mahmud , who had the titular name of Nasir-ud-din Feroze Shah and reigned from 1246 to 1266. As a ruler, Mahmud was known to be very religious, spending most of his time in prayer and was renowned for aiding the poor and the distressed. It was his Deputy Sultan, Ghiyath-ud-din Balban , who primarily dealt with state affairs.
Ghiyath-ud-din Balaban:-
The ninth Sultan was Ghiyath-ud-din Balaban, who had the titular name of Sultan and reigned from 1266 to 1287. Balban ruled with an iron fist and broke up the Chihalgani group of noblemen. He tried to establish peace and order in India and built many outposts with garrisons of soldiers in areas where there had been disorder. Balban wanted to make sure everyone was loyal to the crown, so he established an efficient espionage system.
Muiz-ud-din muhammad Qaiqabab:-
The tenth and final Sultan was Muiz-ud-din muhammad Qaiqabab who had the titular name of Sultan and reigned from 1287 to 1290. Being still young at the time, he ignored all state affairs. After four years, he suffered a paralytic stroke and was later murdered in 1290 by a Khalji chief. His three-year-old son Kayumars nominally succeeded him, but the Slave dynasty had ended with the rise of the Khaljis.
