Sri Maharaja Sang Sapurba Paduka Sri Trimurti Tri Buana, (1245–1316) also known as Sri Nila Pahlawan, is a figure in the Malay Annals and Tarambo Minangkabau highly revered as the legendary great ancestor of some of the major dynasties of the Malay world: Singapura, Malacca, Pahang, Johor, Perak, Kelantan, Terengganu and Siak Sri Indrapura. Legend has it that after his accession to Seguntang Hill with his two younger brothers, Sang Sapurba enters into a sacred covenant with Demang Lebar Daun the native ruler of Palembang, which laid the basis of the proper relationship between the Malay rulers and the subjects. The legendary sword believed to be carried by the king, the Cura Si Manjakini, now forms part of the royal regalia of the Perak Sultanate, whose rulers are said directly descended from the king. Details of the Sang Sapurba stories are mainly composed of folklore and legends, and thus his historical existence is debated and disputed by modern historians. Even so, as anthopology professor de Jong argued in her article The Character of Malay Annals, the stories of the Malay Annals could have been realistically mixed with historical figures and events.
