 "Indonesia Raya" ("Great Indonesia") is also the name of the Indonesian national anthem.The Pan-Malay union was based on understandings on similarities in race, shared language, religion and culture among ethnic groups in Maritime Southeast Asia.The ancient concept of "Alam Melayu" or "Nusantara" advocates an historical awareness that the territory of British Malaya, British Borneo and the Dutch East Indies were once united, to a degree, under native empires such as Srivijaya, Majapahit, the Malacca Sultanate, Johor-Riau Sultanate and various other sultanates in Borneo island.
