Plastic surgery first took place in India around 600 B.C. It was first used to reconstruct the noses of criminals, which had been amputated as punishment, using skin from the forehead. (source)

The oldest known repair surgery dates back to 49 B.C., when the Hindu surgeon Susruta carried out an operation to treat intestinal perforations and obstructions by joining together the damaged parts of the intestine after cutting into the abdomen. He sutured the segments by placing the freshly-cut heads of giant black ants on the edges of the opposing sections, demonstrating knowledge of the antiseptic properties of the formic acid that is secreted by the ant heads.

Arabic numerals are not Arabic. While Europe obtained this system from the Arabs, the Arabs in turn obtained this system from the Hindus around the middle of the eighth century. The Hindu writer Aryabhata first described the new system in the year 499. The invention of the sign for zero made arithmetic computation much easier. In contrast, calculation was more awkward in the Roman numeral system. (source)

Babur, the first Moghul emperor of India, marched through the Khyber Pass onto the North Indian plain in 1526. The then North Indian ruler, an Afghan king, Sultan Ibrahim, leading an army of 100,000 men, attacked the invaders and lost, despite the nearly ten-to-one odds in manpower in his favour. The reason for Babur's triumph was an ancient Chinese invention that the Sultan had never heard of - gunpowder.

The political unification of North India began with Akbar, the Moghul emperor (1556-1605). Prior to Akbar, the Muslim rulers of India regarded non-Muslims as second-class citizens who had to pay a poll tax (ziziya) to live in a Muslim land. Akbar, on the other hand, married women of royal Hindu families, gave Hindus access to the inner circles of his court, and abolished the ziziya and the Hindu pilgrimage tax.

Akbar, third Moghul Emperor of India (1556-1605), was not only a brilliant general and ferocious fighter, but also imported rare plants and grasses, grafted trees, crossbred doves, maintained zoological notebooks, commissioned translations of Aristotle and other Greek philosophers, wrote letters to the Pope and to two Spanish kings, and initiated the first Anglo-Indian diplomatic relationship when he corresponded with Queen Elizabeth I.

The fourth Moghul Emperor, Jahangir, who ruled from 1605 to 1627, had a harem of 300 royal wives, 5,000 more women, and 1,000 young men for alternate pleasures. His stables contained 12,000 elephants, 10,000 oxen, 2,000 camels, 3,000 deer, 4,000 dogs, 100 tame lions, 500 buffalo, and 10,000 carrier pigeons. (source)

The Taj Mahal in Agra, one of the world's most beautiful buildings, was built by the Moghul emperor Shah Jahan (1627-1659) as a mausoleum for one of his wives, Mumtaz Mahal, who, on her deathbed in 1631, extracted a promise from her husband to take care of her children and to build a suitable monument for her. Masons from northern India, calligraphers from Baghdad and Shiraz, and various specialists from all around the Muslim world designed and supervised building activities as well as planning the garden. The work was coordinated by Ustad Isa from Lahore. (source)

The first six Moghul Emperors of India ruled in an unbroken succession from father to son for nearly 200 years, from 1526 to 1707, a remarkable feat as there was no tradition of primogeniture and the contest for the throne was often bloody.

The Taj Mahal was scheduled to be torn down in the 1830s so that its marble facing could be auctioned off in London to the landed English gentry. Wrecking machinery was moved into the garden grounds and work was about to begin when word came from London to cancel the demolition. The first auction of marble facades of Indian buildings had been a failure, so tearing down the 200-year-old mausoleum would not be worth it. (source)

Over a period of 500 years, a secret religious sect in India called the Thugs ritually murdered about 12 million people. The term "thug" originally was Hindi for "swindler". Starting in the thirteenth century, the Thugs travelled about India in bands, preying on travellers, whom they would strangle and rob. The Thugs were fanatically devoted to Kali, the Hindu goddess of destruction. They lasted until around the 1830's, when the occupying British destroyed the destructive sect.

He removed a cornea from a recently killed antelope and transplanted it into his pet's eye. The operation was a success, and the pet was able to see. (source)
