Malays (Malay: Melayu) are an ethnic group of Austronesian peoples predominantly inhabiting the Malay Peninsula and parts of Sumatra and Borneo. The Malay ethnic group is distinct from the concept of a Malay race, which encompasses a wider group of people, including most of Indonesia and the Philippines. The Malay language is a member of the Austronesian family of languages. The Malay people are believed to have originated in Borneo and then expanded outwards into Sumatra and later into the Malay Peninsula. These people were descendants of Austronesian-speakers who migrated from the Philippines and originally from Taiwan. The main foundation of this school of thought lies in the fact that the oldest Malay settlements have been discovered in Sumatra and not in the Malay Peninsula. This suggests an upward - south to north - migratory route. Malay culture reached its golden age during Srivijayan times. Malays praticed Buddhism, Hinduism, and their native Animism before converting to Islam in the 15th century.
