Malayisation is a process of assimilation and acculturation, that involves acquisition (Malay:Masuk Melayu, literally "embracing Malayness") or imposition (Malay:Pemelayuan or Melayuisasi) of elements of Malay culture, in particular, Islam and Malay language, as experienced by non-Malay populations of territories controlled or substantially influenced by historical Malay sultanates and modern Malay-speaking countries. It is often described as a process of civilisational expansion, drawing a wide range of indigenous peoples into the Muslim, Malay-speaking polities of Maritime Southeast Asia.
