Mohammad Bin Sam - A period of about one and a half century intervened Mahmud of Ghazna and Muhammad of Ghor.  After 150 years of flourishing reign, Khusru Malik, the last ruler of Ghazna was overthrown by Mohammad bin Sam of Ghor in 1186.  With a high ambition to convert Hindustan, Mohammad Bin Sam decided to battle against various Rajput clans.  After finally defeating Prithviraj at Thanesar (Terain) and capturing Prithviraj to death in 1193, Mohammad of Ghor founded the first Mohammedan Dynasty of Hindustan which in fact starts along with his successor Qutubud-d-din Aibak a former slave bought from Turkistan, fixing his capital at Delhi.  In the following year, he took possession of Benaras, Kanauj, and Marwa and in 1195 AD, Gwalior was annexed.  Qutb-ud-din rose to highest rank because of his skills as a rider, archer and the talent through formal education.  Qutbal-din Aibak who was in command  took Gujarat.   In 1206 AD, Mohammad bin Sam was murdered on his way to Ghazna.

Qutubud-d-din Aibak - As Mohammad bin Sam had no heir to succeed in India, Qutubud-d-din Aibak assumed authority over the Ghorid possessions in India.  But Qutubud-d-din had to face Taj-ud-Din Yildiz of Ghazna who also claimed his former master's Indian possessions.  In 1208, Qutubud-d-din finally defeated Taj-ud-Din Yildiz and succeeded to be an independent ruler.  Qutubud-d-din then occupied Bihar and Bengal.  Qutubud-d-din never lost any battle and was most successful in bringing a large part of India under Islam.

Aram Bakhsh - Qutb-ud-din's untimely death after reigning for four years brought Aram Bakhsh to the throne.  Shams-ud-din Iltumish(1211-36), the son-in-law of Qutubud-d-din Aibak and the governor of Badaun defeated Aram Bakhsh (he was yet another turkish slave) and took over the title of Sultan.  He faced problems in defending the western frontier and muslim nobles were not that trust worthy.  Even to subjugate the Hindu kings was tough, but Iltumish cleverly succeeded and claimed the title of Sultan and laid the foundation of the independent sultanate of Delhi.  During his flourishing twenty six years of reign, the important landmark of India - the Qutub Minar was completely erected within the citadel of Delhi though the work was initiated by his father-in-law Qutubud-d-din Aibak. Delhi was no longer subordinate to Ghazna and the sultanate of Delhi was established during Iltumish's reign.

Raziyyat-ud-Din(1236-40) - In 1236, when Iltumish lay dying, he nominated his daughter Raziyya to succeed him thinking that Raziyya is a better man than her brothers.  The simple mistake of her was that she gave much importance to Yaqut an Abyssinian, and it was for the same reason her nobles "The Forty" raised a rebellion. The Fourty (Chihilgan) were Iltumish's personal slaves and also a talented political fraction who were loyal to Iltumish's family.  The nobles and the Islamic population however could not adjust to the idea of being ruled by woman, the rebellion leader Ikhtiya-ud-din Altunya defeated her troop and captured her as a prisoner.  As a female, she did not reach end of her resource; She married him though in capture and managed to get back to throne!!!  Fate however was not in her favour, soon she was killed by Bahram thus giving up the throne to Bahram.  A simple quarrel of Bahram with his masters "The Forty"  ended up in his death placing a Ala-ud-din Masud on throne.  The drunkard and idolent Masud did not experience the value of the throne and was ended up by "The Forty" replacing Nasir-ud-din, a youth of seventeen.

Nasir-ud-din (1246-66) - The studious new ruler was quite temperate and deeply religious, he had Balban as his wonderful minister.  His untiring energy  did manage to suppress the attacks from Mongols and the rebellions.  He grew stronger day by day thus repelling Mongol attacks and reasserting the authority of the central government among the turbulent Hindus of the Doab.  When Nasir-ud-din's last descendant died in 1266 AD, Balban became king as Ghiyas-ud-din Balban.

Ghiyas-ud-din Balban - Though Balban's throne was secure, India was exposed to ever present danger from Mongol's attacks.  As a king, he was prepared to even hang his unsuccessful general and did not hesitate to punish his subjects if found guilty.  During his reign, roads were cut through jungle to tame the hill tribes.  He experienced sorrow when one of his son and heir Muhammad Khan was killed in the war against Mongol invaders of Multan.  The slave who had risen as a water carrier to huntsman, thus attained supreme power and passed at the age of eighty two leaving his throne to Kaiqubad, the grandson (son of Bughra Khan, then general of Bengal).  Kaiqubad's assasination gave a opportunity to the "Anti Turkhish" Afghan group of nobles to declare Jalal-ud-din Firoz as  the king of Delhi.  The Slave dynasty was thus put to an ultimate end by the Afghan nobles.
