Tahnun bin Shakhbut Al Nahyan


Sheikh Tahnun bin Shakhbut Al Nahyan was the Ruler of Abu Dhabi from 1818–1833. Having deposed his brother Muhammad bin Shakhbut Al Nayhan with his father's support, he ruled in his father's name. Under Tahnun, Abu Dhabi became a Trucial State in 1820, eventually becoming the capital of the United Arab Emirates.

Accession

Tahnun acceded after having driven his brother Muhammad into exile with his father Shakhbut's support. It was, in fact, Shakhbut who was signatory to the landmark General Maritime Treaty of 1820 with the British, following the sack of Ras Al Khaimah and bombardment of coastal communities which took place during the punitive British Persian Gulf Campaign of 1819. However, in an 1824 peace agreement with Sultan bin Saqr Al Qasimi of Sharjah over the forts at Buraimi Oasis, it was Tahnun who signed.

Abu Dhabi attacked

The exiled Sheikh Muhammad bin Shakhbut returned to Abu Dhabi in late 1823, together with a force of Manasir Bedouin and sacked the town. He was driven out, with the loss of 35 men, by Tahnun, who had raced from the interior to meet him. Muhammad made for Sharjah, but was followed by Tahnun and his force and Tahnun demanded Sultan bin Saqr of Sharjah hand him over. Sultan was saved the dilemma when Muhammad once again fled into exile.

Buraimi

As Abu Dhabi grew, many of its inhabitants maintained links to the inland oasis town of Buraimi and Tahnun worked to establish his influence there, brokering a peace between the Na'im of the oasis and their breakaway relatives, the Al Nuami of Ajman and the Al Bu Shamis. A number of interests jostled for Buraimi, including the Sultan of Muscat, the Wahhabis and Sultan bin Saqr of Sharjah, who had established a number of forts in the oasis. Tahnun commanded the loyalty of many of the Bedouin families in the area and established his primacy there when, in 1824, an agreement was forced on Sharjah in which Sultan bin Saqr recognised Tahnun's claim to Buraimi and then demolished the forts he had built there.
Tahnun had three sons, Hamdan, Said bin Tahnun Al Nahyan and Saqr.

Death

Mistrusting his brothers Sheikh Khalifa bin Shakhbut Al Nahyan and Sultan bin Shakhbut, Tahnun kept them away from Abu Dhabi but his father persuaded him to let them return. He discovered them plotting to remove him and imprisoned a number of the plotters. This action spurred the conspirators to action and Tahnun was killed by his two brothers in 1833. Khalifa became the next Ruler.
