Historically, before the arrival and spread of
Islam in the 15th century, and the spread of
Christianity in the 19th century, the inhabitants of the land were either
Hindu-
Buddhists or practised indigenous faiths. In the peninsula,
the rise of islam is said to have begun in 1409 after
Parameswara became
Sultan of Malacca and converted to
Islam after marrying a princess from the
Samudera Pasai Sultanate. Since then, other Sultanates in the Malay peninsula have adopted Islam. Also since then, and continuing after the independence of Malaysia, Islam played a central role in Malaysian society. Similarly in East Malaysia, folk religion was widespread prior to the arrival of Christian missionaries from Europe. The practice of
headhunting was quite common in these societies. In
Sabah there are still followers of the
indigenous religion Momolianism: the
Kadazan-Dusuns worshipped Kinoingan, a rice deity, and celebrate
Kaamatan, the harvest festival, every year. During Kaamatan, there are certain rituals which have to be carried out by the high priestesses known as
bobohizans (or
bobolian in the Bundu-Liwan dialect of
Dusun). Today, most Kadazan-Dusuns have adopted Christianity, but some still celebrate Kaamatan. However, the number of bobohizans has tremendously dropped and this role is on the brink of extinction. In
Sarawak, it has been said that the animism practised by the
Ibans and other related groups is the most developed, elaborated, and intellectualised in the world. Folk religious practice in East Malaysia is related to the religion of
Kaharingan in
Kalimantan,
Indonesia, which has been recognised as an official religion by the Indonesian government. However, the rituals involved are not entirely similar with variations depending on the ethnic subgroups which practise them. ==Shamanism and traditional healing==
