"The 17th and the 18th centuries were not that great, but the 15th and 16th centuries were full of interesting anecdotes. The spice trade was booming. The Mamluks, slave soldiers of the Muslim sultans who were converted to Islam and trained as a crack force, fought the Mongols and even defeated the crusaders. Historically, Asia and Europe were in a ferment and it was an exciting period in world history," Daruwalla, a former Indian Police Service officer, has been quoted as saying by the IANS news agency. His book *For Pepper and Christ*, a historical novel, was released in 2009 in New Delhi.
