House of Bolkiah in the context of "Sharif Ali"

The sultan of Brunei (Malay: Sultan Brunei, Jawi: سلطان بروني‎) is the monarchical head of state of Brunei and head of government in his capacity as prime minister of Brunei. Since independence from the British in 1984, only one sultan has reigned, though the royal institution dates back to the 14th century. The sultan of Brunei can be thought of as synonymous with the ruling House of Bolkiah, with generations being traced from the first sultan, Muhammad Shah, temporarily interrupted by the thirteenth sultan, Abdul Hakkul Mubin, who in turn was deposed by a member of the House of Bolkiah. The sultan's full title is His Majesty The Sultan and Yang di-Pertuan of Brunei Darussalam. The Sultan of Brunei was also regarded as the Sultan of Sarawak, Labuan and Sabah before the Europeans took over the three territories.

The Banu Qatadah (Arabic: بنو قتادة, romanized: Banū Qatādah, lit. 'Sons of Qatadah'), or the Qatadids (Arabic: القتاديون, romanized: al-Qatādayūn), were a dynasty of Hasanid sharifs that held the Sharifate of Mecca continuously from 1201 until its abolition in 1925. The Qatadids were the last of four dynasties of Hasanid sharifs (preceded by the Jafarids/Musawids, Sulaymanids, and the Hawashim) that all together ruled Mecca since about the mid-10th century. The progenitor of the dynasty was Qatadah ibn Idris, who took possession of the holy city from the Hawashim in 1201. The Emirate remained in the possession of his descendants until 1925 when the last Sharif of Mecca, Ali ibn al-Husayn, surrendered the Kingdom of Hejaz to Ibn Saud, Sultan of Nejd. The House of Bolkiah, which rules Brunei, claims Qatadid descent and Sayyid status from their ancestor Sharif Ali's grandfather Emir Rumaythah.
