The Kingdom of Singapura (Malay: Kerajaan Singapura) was a Malay polity believed to have been founded as a Hindu–Buddhist kingdom during the early history of Singapore on the island of Temasek, lasting from 1299 until its decline and fall between 1396 and 1398. Conventional view marks c. 1299 as the founding year of the kingdom by Sang Nila Utama (also known as "Sri Tri Buana"), whose father is Sang Sapurba, a semi-divine figure who according to legend is the ancestor of several Malay monarchs in the Malay world.
The historicity of this kingdom based on the account given in the Malay Annals is uncertain and many historians only consider its last ruler, the Muslim convert Parameswara (or Sri Iskandar Shah), to be a historically attested figure in his role as the first ruler of the Malacca Sultanate. Archaeological evidence from Fort Canning Hill and the nearby banks of the Singapore River has nevertheless demonstrated the existence of a thriving settlement and a trade port in the 14th century, corroborating the eyewitness testimony of Yuan dynasty sojourner Wang Dayuan concerning the settlements of Long Ya Men and Ban Zu upon Temasek.
