The Kai Islands (also Kei Islands) of Indonesia are a group of islands in the southeastern part of the Maluku Islands, located in the province of Maluku.[1][2] The Moluccas have been known as the Spice Islands due to regionally specific plants such as nutmegmace, and cloves that originally intrigued the European nations of the 16th century.[3]

Though originally Melanesian,[4] many islanders were exterminated in the 17th century during the spice wars, particularly in the Banda Islands. A second influx of Austronesian immigrants began in the early 20th century under the Dutch and continued in the Indonesian era.
