Sultan Bolkiah's tombstone
|5th Sultan of Brunei|
|Heir apparent||Abdul Kahar|
|Spouse||Puteri Laila Menchanai, Princess of Sulu|
Sultan Bolkiah was the 5th Sultan of Brunei. He ascended the throne upon the abdication of his father, Sultan Sulaiman, and ruled Brunei from 1485 to 1524. His reign marked the Golden Age of Brunei  and saw the Sultanate became the superpower of the Malay archipelago. Bolkiah frequently traveled abroad to gain new ideas for the development of the country, as well as seeking suggestions from his various chiefs. It is said that his name was kept by his father after the Ba'Alawi Sayyed clan Ba-Awalqhiyyah who had gained control over much of the Yemeni kingdom of Hadhramaut.
Sultan Bolkiah's victory over Seludong (modern-day Manila)  by defeating Rajah Suko of Tundun in Luzon and as well as his marriage to Laila Menchanai, the daughter of Sulu Sultan Amir Ul-Ombra, widened Brunei's influence in the Philippines.
This increased Brunei's wealth as well as extending Islamic teachings in the region, resulting in the influence and power of Brunei reaching its peak during this period. Bolkiah's rule reached essentially all of coastal Borneo,  as far south as Banjarmasin,  and as far north as the island of Luzon, including Seludong (present-day Manila) in the Philippines. 
Bolkiah was married to Laila Menchanai, the daughter of Sulu Sultan Amir Ul-Ombra and Datu Kemin.
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 Hadhramawt 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 started until 1807 CE.
