During Aurangzeb's reign, it was captured on 7 September 1695 by the English pirate Henry Every en route from present-day Mocha, Yemen to Surat, India. It was built on the order of Empress Mariam-uz-Zamani, great grandmother of Aurengzeb, after the capture of her ship named Rahimi.

A debasement of coinage is the practice of lowering the intrinsic value of coins, especially when used in connection with commodity money, such as gold or silver coins, while continuing to circulate it at face value.
