Such a classification was only an administrative decision. This was not enough to develop a common identity among the various Orang Asli groups. In real life, each tribe has its own language and culture, feels like a community different from others. The first two main tribes like The Semang and Senoi groups, being Austroasiatic also known as "Mon-Khmer language" speakers, are the indigenous peoples of the Malay Peninsula. The Proto-Malays (Third Tribe), who speak Austronesian languages, migrated to the area between 2500 and 1500 BC. The Orang Asli were originally considered ethnic Malay, but reclassified as part of Orang Asli by the British colonial authorities due to the similarity of their socio-economic and lifestyles with the Senoi and Semang. There's also various degrees of admixture within all 3 groups. It was only over time that the indigenous peoples began to identify themselves under a common name "Orang Asli", by unconsciously adopting this official ethnic marker in order to differentiate themselves from the country's dominant population, the "others". Such self-identification was conditioned by the need to defend one's personal and collective identity in the struggle against the power of "foreigners", in particular, the state. For them, the identity of the "Orang Asli" means their "nativeness" belongs to the country's indigenous population.
