, often referred as "Wahhabis". Embracing his ideals, Qasimis robustly championed the doctrines of the ''Muwahhidun'' in the Gulf region and became a close ally of the
Emirate of Diriyah.
By the early 19th century,
Emirate of Diriyah had begun appointing Qasimi governors to implement Wahhabi religious doctrines and defend their interests. Thus, while Dir'iyah directly sought to consolidate their Arabian territories and its economic sovereignty, Qawasim acted as Wahhabi

, also a rival of the Emirate of Dir'iyah, had been the traditional enemy of the Qawasim over issues related to border disputes, religious differences and naval dominance in the Gulf. Al Qasimi's control of trade in the Persian Gulf area led to wars with Oman and eventually with Oman's ally, Britain, and to the Al Qasimi being labelled by the British as pirates. This led to the identification of the southern shore of the Persian Gulf as the 'Pirate Coast', although following the
General Maritime Treaty of 1820 and the 1853 Perpetual Maritime Peace, the various coastal emirates in the area became known as the
Trucial States

Beginning from 1804, there emerged a spike in Wahhabi-Qasimi naval attacks on
British fleet and trading ships. Following decades of incidents where British shipping had fallen foul of the aggressive Al Qasimi, a first British expeditionary force embarked for Ras Al Khaimah in 1809, the
Persian Gulf campaign of 1809. This campaign led to the signing of a peace treaty between the British and Hussan Bin Rahmah, the Al Qasimi leader.

in native affairs. Warden also successfully argued against a proposal to install the Sultan of Muscat as Ruler of the whole peninsula. Warden's arguments and proposals likely influenced the shape of the eventual treaty concluded with the Sheikhs of the Gulf coast.
That 1820 treaty asserted, 'There shall be a cessation of plunder and piracy by land and sea on the part of the Arabs, who are parties to this contract, for ever.' It then goes on to define piracy as being any attack that is not an action of 'acknowledged war'. The 'pacificated Arabs' agreed, on land and sea, to carry a flag being a red rectangle contained within a white border of equal width to the contained rectangle, 'with or without letters on it, at their option'. This flag was to be a symbol of peace with the British government and each other.
The treaty having been signed by Keir Grant and all of the Trucial Rulers, the Government in Bombay made clear that while it was happy with Grant's management of the military expedition, it was most dissatisfied with his leniency over the coastal tribes and desired, 'if it were not too late, to introduce some conditions of greater stringency'. Grant's response was spirited, pointing out that to have enforced extreme measures would have meant pursuing the chiefs into the interior rather than accepting their voluntary submission. This would have contravened Grant's instructions. In the end, Bombay allowed the treaty to stand.
