“When one thinks of mass murder, Hitler comes to mind. If not Hitler, then Tojo, Stalin, or Mao. Credit is given to the 20th-century totalitarians as the worst species of tyranny to have ever arisen. However, the alarming truth is that Islam has killed more than any of these, and may surpass all of them combined in numbers and cruelty. The enormity of the slaughters of the ‘religion of peace’ are so far beyond comprehension that even honest historians overlook the scale.” – Mike Conrad, The Greatest Murder Machine in History [1]
“The Mohammedan conquest of India was probably the bloodiest story in history.” – Will Durant, American historian [2]
“…The Indian (subcontinent) population decreased by 80 million between 1000 (conquest of Afghanistan) and 1525 (end of Delhi Sultanate)” – Koenraad Elst, Negationism in India [3]

The Slave (Mamluk) Rulers – 13th Century
Excerpts from “The Magnitude of Muslim Atrocities” [4]
Shamsuddin Iltutmish who succeeded Aibak at Delhi invaded Malwa in 1234 CE. He destroyed an ancient temple at Vidisha. Badauni reports in his ‘Muntakhab-ut-Tawarikh’:
“Having destroyed the idol temple of Ujjain which had been built six hundred years previously, and was called Mahakal, he leveled it to its foundations, and threw down the image of Rai Vikramajit from whom the Hindus reckon their era, and brought certain images of cast molten brass and placed them on the ground in front of the doors of mosques of old Delhi, and ordered the people of trampling them underfoot.”
Muslim power in India suffered a serious setback after Iltutmish. Balban had to battle against a revival of Hindu power. The Katehar Rajputs of what came to be known as Rohilkhand in later history had so far refused to submit to Islamic imperialism. Balban led an expedition across the Ganges in 1254 CE. According to Badauni,
“In two days after leaving Delhi, he arrived in the midst of the territory of Katihar and put to death every male, even those of eight years of age, and bound the women.”
But in spite of such wanton cruelty, Muslim power continued to decline till the Khaljis revived it after 1290 CE.
