The last Khalji sultans :-
Aladdin Khalji died in December 1315. Thereafter, the sultanate witnessed chaos, coup and succession of assassinations. Malik Kafur became the sultan but lacked support from the amirs and was killed within a few months.
Over the next three years, another three sultans assumed power violently and/or were killed in coups. Following Malik Kafur's death, the amirs installed a six-year-old named Shihab-ud-din Omar as sultan and his teenage brother, Qutb ud din Mubarak Shah, as regent. Qutb killed his younger brother and appointed himself sultan. To win over the loyalty of the amirs and the Malik clan, Mubarak Shah offered Ghazi Malik the position of army commander in the Punjab. Others were given a choice between various offices and death. After ruling in his own name for less than four years, Mubarak Shah was murdered in 1320 by one of his generals, Khusraw Khan. Amirs persuaded Ghazi Malik – who was still army commander in the Punjab – to lead a coup. Ghazi Malik's forces marched on Delhi, captured Khusraw Khan and beheaded him. Upon becoming sultan, Ghazi Malik renamed himself Ghiyath al-Din Tughluq. He would become the first ruler of the Tughluq dynasty.
Slavery :-
Within Sultanate's capital city of Delhi, during Alauddin Khalji's reign, at least half of the population were slaves working as servants, concubines and guards for the Muslim nobles, amirs, court officials and commanders. Slavery in India during Khalji, and later Islamic dynasties, included two groups of people - persons seized during military campaigns, and people who failed to pay tax on time. The first group were people seized during military campaigns. The second group of people were revenue defaulters. If a family failed to pay the annual tax in full on time, their property was seized and even some cases all their family members seized then sold as slaves. The institution of slavery and bondage labor became pervasive during the Khalji dynasty; male slaves were referred to as banda, qaid, ghulam, or burdah, while female slaves were called bandi, kaniz or laundi.
Architecture :-
Ala-ud-din Khalji is credited with the early Indo-Mohammedan architecture, a style and construction campaign that flourished during Tughlaq dynasty. Among works completed during Khalji dynasty, are Alai Darwaza - the southern gateway of Qutb complex enclosure, the Idgah at Rapri, and the Jamat Khana (Khizri) Mosque in Delhi. The Alai Darwaza, completed in 1311, was included as part of Qutb Minar and its Monuments UNESCO World Heritage site in 1993.
Perso-Arabic inscriptions on monuments have been traced to the Khalji dynasty era.
