Most of the islands are mountainous, some with active volcanos. The vegetation of the small and narrow islands, with their wet climate, is very luxuriant. It includes rainforests, sago, rice, and the famous spices; including nutmeg, cloves, and mace. Though originally Melanesian, the people of many island clans, especially in the Banda Islands, died in the 17th century. A second group of Malay people arrived in the early 20th century under the Dutch and this has continued in the Indonesian era.
Politically, the Maluku Islands formed a single province of Indonesia from 1950 until 1999. In 1999 the North Maluku (Maluku Utara) and Halmahera Tengah (Central Halmahera) regency were split off as a separate province. The islands are now divided between two provinces, Maluku and North Maluku. Most of the people of these islands follow Islam. There is also a Christianminority because of Western European Christian Protestant missionaries in this region. Between 1999 and 2002 there was deadly fighting between the Muslim population and the Christians. Both groups had been peaceful before. The capital of North Maluku island is Ternate.
