[6] Ras Al Khaimah has been the site of continuous human habitation for 7,000 years, with archaeological finds dating back to the Neolithic.
[7] The northern area of the city today known as Ras Al Khaimah was previously the location of the important Islamic era settlement and port of Julfar.
The British operation continued to Lingeh on the Persian coast which was, like the Greater and Lesser Tunbs islands, administered by the Al Qasimi.
[11][12] By the morning of 14 November, the military expedition was over and the British forces returned to their ships, having suffered light casualties of five killed and 34 wounded.
On the fall of Ras Al Khaimah, three cruisers were sent to blockade Rams to the North and this, too was found to be deserted and its inhabitants retired to the 'impregnable' hill-top fort of Dhayah.
There, 398 men and another 400 women and children held out, without sanitation, water or effective cover from the sun, for three days under heavy fire from mortars and 12-pound cannon.
[17] The two 24-pound cannon from HMS Liverpool which had been used to bombard Ras Al Khaimah from the landward side were once again pressed into use and dragged across the plain from Rams, a journey of some four miles.
After enduring two hours of sustained fire from the big guns, which breached the fort's walls, the last of the Al Qasimi surrendered at 10.30 on the morning of 22 December.
[18] The treaty stipulated the end of piracy and slavery, and laid the foundation for the British protectorate over the Trucial States that lasted until December 1971.
A British protectorate from this point forward, as one of the Trucial States, in 1869, Ras Al Khaimah became fully independent from neighbouring Sharjah.
The last of the Trucial States to join the newly independent United Arab Emirates, on 10 February 1972, Ras Al Khaimah, under the leadership of Sheikh Saqr bin Mohammad Al Qasimi, joined the United Arab Emirates following the Iranian seizure of Abu Musa and the Greater and Lesser Tunbs.
