The Aceh War, also known as the Dutch War or the Infidel War (1873-1914), was an armed military conflict between the Sultanate of Aceh and the Netherlands which was triggered by discussions between representatives of Aceh and the U.S. in Singapore during early 1873. The war was part of a series of conflicts in the late 19th century that consolidated Dutch rule over modern-day Indonesia, concurrent with the 1906 and the 1908 interventions in Bali.
