Konfrontasi
1963–1966 military conflict
The Konfrontasi, also known as the Indonesia–Malaysia confrontation or Borneo confrontation, was an armed conflict from 1963 to 1966 that stemmed from Indonesia's opposition to the creation of the state of Malaysia. Vital precursors to the conflict included Indonesia's policy of confrontation against Dutch New Guinea from March to August 1962 and the Indonesia-backed Brunei revolt in December 1962. Malaysia had direct military support from the United Kingdom, Australia, and New Zealand.
