Jalaluddin Firoz Khalji, the founder of the Turkish dynasty, ascended the throne at the age of seventy and established Khalji dynasty  by defeating the descendants of Balban.  The assumption of royal authority by Jalal-ud-din Khalji  was not generally accepted by Turkish Amirs who hated the Kaljis as low born Afghans.  Before his reign, Jalal-ud-din had won many battles, but he was against shedding the blood of  any muslims for political or territorial gains.  He made Ala-ud-din the governor of Avadh in addition to Kara.  The over ambitious Ala-ud-din had heard of wealthy Deccan and attacked Deccan with a huge army and defeated Raja Ramchandra of Devagiri.  When the affectionate father-in-law Jalal-ud-din had gone to receive and greet Ala-ud-din on his victory of Deccan, the vigorous Ala-ud-din put a spear through his head and assassinated him thus proclaiming the throne of Delhi.

Talented Ala-ud-din, (the nephew of Jalaluddin ) succeeded Jalaluddin in 1296, but had to face more than a dozen of invasions from Mongol.  In one event Mongols were utterly defeated by Alaluddin. The later attacks from Mongols were completely put off by his carefully chosen brave generals and by massacring the Mongols who had sought Islam. It is these war skills filled confidence in him to invade Deccan in 1294 AD.  In 1297-1298 he acquired Gujarat, Somanath and Surath. Under his command, General Malik-Kafur invaded Deccan again in 1309 AD bringing in Warangal and Devagiri and in 1310  the entire eastern territory and the Bellal kingdom (Dwarasamudra).  Malik Kafur was thus responsible for the conquest of Southern India and within less than ten years he rose to the rank of Naib  from slave.  The success of Malik Kafur made him so strong that Ala-ud-din became virtually a puppet in his hands and finally brought about his death by poisoning.

After the death of Ala-ud-din, Malik Kafur appointed Ala-ud-din's minor son Shihab-ud-din Umar as the successor.  All the powers were in hand of the regent Malik Kafur as Umar was just six year old.  After Malik Kafur's death, Shihab-ud-din dethroned and gave way to his brother Mubarak to reign. Mubarak took up the title of Mubarak Shah (1st of April 1316) and liberalized the taxation and won peoples good will. Soon he got into the habit of drinking and merry making with his nobles and revealed the weakness to the rebels.  Soon Devagiri and Rajputana declared their independence. He was finally stabbed by Khusro on 14th of April 1320.  Soon, Nasirud-din Khusro ascended the throne, but could not hold it for more than few months as there was a opposition from Turrkish nobles who were questioning his authority.   The Turkish noble and the governor of Panjab Ghazi Malik marched to Delhi with his army and defeated Khusro and killed him.

Nasirud-din Khusru Shah the last ruler of the Khalji dynasty breathed his last and Taghlaqs rose to power with the leadership of Ghiyas-ud-din Taghlaq Shah-I.
