Prior to his reign, he was called Awang Pateh Berbai or Pateh Berbai in short. According to the
Syair Awang Semaun, this first community was founded because 14 siblings wanted to start and construct a new village. Pateh Berbai led the Sakai tribe's retinue to the
Brunei River, where they searched for a suitable spot for a colony. They discovered a site that was strategically located, nestled between hills, and had access to water from a neighbouring river. Tugan, the chief of the Retus and the leader of the Igan people in
Melanau, tried to overthrow Awang Alak Betatar's authority with the help of his in-law Besiong. The soldiers of Awang Alak Betatar, led by Pateh Berbai, overcame them. The history of Brunei is explained in the
Syair Awang Semaun, which was written during the reign of Awang Alak Betatar and his siblings. Awang Semaun at
Kota Batu; Pateh Mambang and Pateh Tuba at
Luba; Pateh Sangkuna and Pateh Manggurun at
Saba; Pateh Malakai at
Bukit Panggal; Pateh Pahit at
Labuhan Kapal; Damang (Damong) Sari at Bukit Salilah; Pateh Sindayung at
Panchor Papan, Demang Lebar Daun, Hapu Awang, Pateh Berbai; and Pateh Laila Langgong are among the characters in the poem. == Reign ==
