Orang Asli found in Peninsular Malaysia. Orang Asli kept to themselves until the first traders from India arrived in first millennium AD.
These slave-raiders were mainly local Malays and Bataks, who considered the Orang Asli as 'kafirs', 'non-humans', 'savages' and 'jungle-beasts.' The modus operandi was basically to swoop down a settlement and then kill off all the adult men. Women and children were captured alive as they are 'easier to tame.' The captives Orang Asli slaves were sold off or given to local rulers and chieftains to gain their favour. Slaves
Orang Asli living in remote forest areas engaged in some trading with the Malays, with jungle produce being exchanged for salt, knives and metal axe-heads. There was also evidence of trade in blowpipes and blowpipe-bamboo among certain tribes. It has also been shown that the Orang Asli have played a significant role in the Malay Peninsula's economic history as collectors and primary traders as early as the 5th Century A.D. An early 19th century report also tells of Negritos providing forest products as tribute to the Malay chiefs of the river basins they resided in.
their three categories are not due to linguistic differences but merely sociological. The Semelai language, for example, is part of the Austro-Asiatic language group, whereas the other Proto-Malay groups, such as the Temuan language, are part of the Austronesian language group. The Semelai and the majority of Orang Asli sub-ethnics speak languages classified as Aslian languages. This is further divided into the Jahaic languages (North Aslian), Senoic languages, Semelaic languages (South Aslian), and Jah Hut. The languages which fall under the Jahaic language group are the Che Wong, Jahai, Bateq, Kensiu, Kintak, and Menriq languages. The Lanoh language, Temiar language, and Semai language fall into the Senoic language category. Languages that fall into the Semelaic group include the Semelai language, Semoq Beri language, and Besisi language (language spoken by the Mah Meri group). Meanwhile, some Orang Asli minorities speak languages classified as Aboriginal Malay languages. This includes the Jakun and Temuan languages among others.Besides these, most Orang Aslis are fluent in the Malay language, the official language of Malaysia.
many of them have embraced monotheistic religions such as Islam and Christianity following some active state-sponsored dakwah by Muslims, and evangelism by Christian missionaries.
