 Give a detailed account of the expansion of the Delhi Sultanate under the Khaljis.

A.  West And Central              
                            The expansion of the Delhi Sultanate started under the reign of Allauddin Khaliji. After consolidating his position and firmly establishing himself at Delhi, he undertook the first expedition in the region of Gujarat in 1299 as he was attracted by the wealth of Gujarat due to flourishing trade. After plundering Gujrat, the administrative control of Gujarat was entrusted to Alp Khan as governor. In the Western region, the next kingdom to fall was that of Malwa in 1305, It was an extensive region and was governed from the capital Mandu by Rai Mahalak Dev. The province of Malwa, after its fall, was given for administration to Ainul Mulk who was known to have soon brought Ujjain, Dhar, and Chadderi, too, under his control. Malwa was followed by Siwana, a town situated some eighty kilometers to the south-west of Jodhpur and the administration was given to Kamaluddin Gurg.  In the same year (1309), Jalor was attacked and its ruler Kanhar Dev was killed in the battle and the fort annexed to the Sultanate under the control of Karnaluddin Gurg.

North West and North
           Suppressing the prospects of revolt by the surviving member of Jalaluddin's family who had fled to Multan, Allauddin sent an expedition there thus consolidating Multan with Delhi Sultanate. In 1300, Alauddin sent Ulugh Khan to march against Ranthambhor ruled by Rai Harnir. Nusrat Khan, then posted at Awadh, joined Ulugh Khan. The Imperial army captured Jhain on the way and then laid a siege. The siege lasted for over six months and Ranthambhor was won as Hamir Dev died fighting. In pursuance of the policy, Alauddin attacked the kingdom of Chittor in 1303 and after several attempts succeeded as the ruler surrendered and Khizr Khan was assigned the governorship of, the territory.  By the end of the first decade of Alauddin's rule, the frontiers of the Delhi Sultanate had expanded to cover almost the whole of north, west and central India.

Deccan and Southward
                    The next military campaign in the Deccan was planned by Alauddin against Rai Ram Chandra Dev of Devagiri in 1306-7. An immediate cause for this was an unduly long delay in sending the annual tribute to Delhi in 1296. The Deccan campaign was given to Malik Kafur, while directions were sent to Ainul Mulk Multani and Alp Khan for providing assistance. Rai Ram surrendered and Devagiri became protectorate paying annual tributes besides parting with hefty wealth. The acquisition of wealth from southern kingdoms & not actual territorial annexation seems to have been the prime motive in sending these expeditions. Accordingly, in October 1309 be imperial army began its southward march under the command of Malik Kafur. Enroute a surprise assault was made by Malik Kafur on the fort at Sirpur (in Adilabad District). The nobles of Sirpur fled to Rai Rudra Dev of Warangal and the fort was captured by the imperial army.  By the middle of January 1310, the marching army had reached the suburbs of Warangal. On 14 February 1310, Kafur attacked the fort. The war came to an end because Rai Rudra Dev decided to surrender. He agreed to part with his treasures & pay an annual tribute as a token of submission. The province was not territorially annexed but accorded the status of a protectorate. Buoyed by the success at Warangal, a military expedition was now launched further south of Warangal against Dwarasamudra under Malik Kafur. The fort was besieged in February 1311 and was surrendered the next day by Ballala Dev, the ruler of Dwarasamudra. Encouraged by his success in Dwarasamudra, Malik Kafur decided to move further South to Madura, the capital of the Pandyas and captured it without resistance.  Alauddin's Deccan and southward campaigns were aimed at achieving two basic objectives:
 (i) formal recognition of the authority of Delhi Sultan over these regions and
(ii) the amassing of maximum wealth at the minimal loss of life.
This is how the Delhi Sultanate expanded under Khalji's.
