Muhammad Hassan (Brunei)

His Highness was the son of Saiful Rijal, the 7th Sultan of Brunei.

• He introduced the Hukum Kanun Brunei, which is similar to Undang-Undang Melaka.
• He installed another two positions of Viziers, Pengiran Di-Gadong and Pengiran Pemancha.[1]

On his coming to Sulu from Brunei around 1609, Raja Bongsu-I also was brought along his royal symbol's called Pulau Janggi (in Sulu) and Sepong Janggi ( in Brunei). Its 1/3 of a Coco de mer seed fruit. This royal symbol proved that Pangiran Shahbandar Maharajalela @ Raja Bongsu-I belonged to the Brunei Sultanate royal blood. Since then, this royal symbol was mandated to hold by The Maharajah Adinda family (the Sulu Sultanate 2nd heir-apparent) and NOT by the Kiram or the Shakiraullah families (the Sulu Sultanate 1st Heir-apparent).

In 1978, this royal symbol was sent to Brunei Museums for "Safe-Keeping" by the Maharajah Adinda true heir, DATU ALIUDDIN Bin Datu Muhammad Sie ibni Maharajah Adinda Sultan Muhammad Aranan/ Adanan Puyo ibni Raja Muda Datu Bantilan @ Datu Badaruddin ibni Sultan Alimuddin-II ibni Sultan Bantilan Muizuddin ibni Sultan Badaruddin-I ibni Sultan Sultan Salahuddin-Karamat ibni Sultan Mawalil-Wasit-I @ Pangiran Shabandar Maharajalela @ Raja Bongsu-I ibni Sultan Muhammad Hassan. (Refer to: Brunei Muzeums record).

By the death of Datu Aliuddin Bin Datu Muhammad Sie in 2007, his elder son's Datu Zainal Ali Bin Datu Aliuddin then succeeding the Maharajah Adinda families legacy.

The earliest historical record of the Sultans of Brunei is not clearly known due to the poor early documentation of Brunei's history. Many elder members of the House of Bolkiah claim that their ancestors were the BaHassan and BaAlawi Saadah from Tarim and Hadhramaut in Yemen. In addition there has been an effort to Islamise the history, with the "official history" not matching up with verifiable foreign sources. The Batu Tarsilah, the genealogical record of the kings of Brunei, was not established until 1807 CE.
