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 United Kingdom 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. Cut Nyak Dhien or Tjoet Nja Dhien (Lampadang, 1850  November 6, 1908) was a leader of the Acehnese guerrilla forces during the Aceh War. Following the death of her husband Teuku Umar, she led guerrilla actions against the Dutch for 25 years. She was posthumously awarded the title of National Hero of Indonesia on May 2, 1964 by the Indonesian government.
