Al Qawasim in the context of "Emirate of Sharjah"

Piracy in the Persian Gulf describes the naval warfare that was prevalent until the 19th century and occurred between seafaring Arabs in Eastern Arabia and the British Empire in the Persian Gulf. It was perceived as one of the primary threats to global maritime trade routes, particularly those with significance to British India and Iraq. Many of the most notable historical instances of these raids were conducted by the Al Qasimi tribe. This led to the British mounting the Persian Gulf campaign of 1809, a major maritime action launched by the Royal Navy to bombard Ras Al Khaimah, Lingeh and other Al Qasimi ports. Some critics of the historical narrative, such as Sharjah ruler Sultan bin Muhammad Al Qasimi in his book The Myth of Piracy in the Gulf, argue that the allegations of piracy were exaggerated by the East India Company to cut off untaxed trade routes between the Middle East and India.

Piratical activities were common in the Persian Gulf from the late 18th century to the mid-19th century, particularly in the area known as the Pirate Coast which spanned from modern-day Qatar to Oman. Piracy was alleviated from 1820 with the signing of the General Maritime Treaty, cemented in 1853 by the Perpetual Maritime Truce, after which the Pirate Coast began to be known by the British as the Trucial Coast (present-day United Arab Emirates).
