The Aru Islands have a long history as a part of extensive trading networks throughout what is now eastern Indonesia. Precolonial links were especially strong to the
Banda Islands, and
Bugis and
Makasarese traders also visited regularly. The traditional society was not pronounced hierarchical, being based on lineage-based clans where the members shared duties of hospitality and cooperation. These island communities were divided into two ritual bonds called Ursia and Urlima, a socio-political system found in many parts of Maluku. Such alliances were connected to pre-European trade networks. The islands were sighted and also possibly visited by some Portuguese navigators, such as Martim Afonso de Melo, in 1522–24, who sighted the islands and wintered on a nearby island or of the Aru archipelago itself, and possibly by
Gomes de Sequeira, in 1526, as is pointed out in the cartography of the time. The Spanish navigator
Álvaro de Saavedra sighted the islands on 12 June 1528, when trying to return from
Tidore to
New Spain. The islands were
colonized by the
Dutch, beginning with a contract with the west coast villages in 1623, though initially the
Dutch East India Company (VOC) was one of several trading groups in the area, with limited influence over the islands' internal affairs. Aru was monitored by the
VOC establishment in the
Banda Islands, and yielded a variety of products including
trepang,
birds-of-paradise,
parrots, pearls,
sago, turtle-shell, and slaves. A Dutch post was established on
Wokam Island in 1659, and a small fort was subsequently constructed there.
Islam as well as
Reformed Protestantism began to make small numbers of converts in the 1650s. Discontent with the commercial monopolies imposed by the VOC came to a boiling point in the late 18th century. The anti-Dutch rebellion of the
Tidore prince
Nuku (d. 1805), which engulfed much of Maluku, also affected Aru. The Muslim population of Ujir Island accepted Nuku's brother Jou Mangofa as their king, exterminated the Dutch garrison in 1787, and were able to dominate large parts of the islands. After several failed attempts, the Dutch of Banda managed to suppress the rebels in 1791. However, they soon ran into new trouble with the coastal populations in the east, and their control of Aru affairs was disrupted by British intervention in the East Indies after 1795. After being left to its own devices for many years, Aru was again visited in 1824 by the Dutch naval officer A.J. Bik, who concluded a number of agreements with local chiefs. In 1857 the famous naturalist
Alfred Russel Wallace visited the islands. His visit later made him realize that the Aru Islands must have been connected by a land bridge to mainland New Guinea during the ice age. In the nineteenth century, Dobo, Aru's largest town, temporarily became an important regional trading center, serving as a meeting point for Dutch, Makasarese, Chinese, and other traders. The period from the 1880s to 1917 saw a backlash against this outside influence by a spiritually-based movement among local residents to rid the islands of outsiders. == Economy ==
