Alauddin Khalji :-
Alauddin Khalji reigned for 20 years. He attacked and seized Hindu states of Ranthambhor (1301 AD), Chittorgarh (1303), Māndu (1305) and plundered the wealthy state of Devagiri, also withstood two Mongol raids. Ala al-din is also known for his cruelty against attacked kingdoms after wars. Historians note him as a tyrant and that anyone Ala al-din Khalji suspected of being a threat to this power was killed along with the women and children of that family. In 1298, between 15,000 and 30,000 people near Delhi, who had recently converted to Islam, were slaughtered in a single day, due to fears of an uprising. He also killed his own family members and nephews, in 1299-1300, after he suspected them of rebellion, by first gouging out their eyes and then beheading them.
In 1308, Alauddin's lieutenant, Malik Kafur captured Warangal, overthrew the Hoysala Empire south of the Krishna River and raided Madurai in Tamil Nadu. He then looted the treasury in capitals and from the temples of south India. Among these loots was the Warangal loot that included one of the largest known diamond in human history, the koh-i-noor. Malik Kafur returned to Delhi in 1311, laden with loot and war booty from Deccan peninsula which he submitted to Aladdin Khalji. This made Malik Kafur, born in a Hindu family and who had converted to Islam before becoming Delhi Sultanate's army commander, a favorite of Alauddin Khalji.
In 1311, Alauddin ordered a massacre of between 15,000 and 30,000 Mongol settlers, who had recently converted to Islam, after suspecting them of plotting an uprising against him.
Koh-i-Noor :-
The diamond was originally owned by the Kakatiya dynasty Probably mined in Golconda , India.
Koh-i-Noor is Persian for "Mountain of Light"; it has been known by this name since the 18th century. It changed hands between various factions in modern-day India, Pakistan, Iran, and Afghanistan, until being ceded to Queen Victoria after the British conquest of the Punjab in 1849.
