WThis is a list of wars involving Malaysia.
WThe Brunei revolt was a December 1962 insurrection in the British protectorate of Brunei by opponents of its monarchy and its proposed inclusion in the Federation of Malaysia. The insurgents were members of the TNKU, a militia supplied by Indonesia and linked to the leftwing Brunei People's Party (BPP), which favoured a North Borneo Federation. The TNKU began co-ordinated attacks on the oil town of Seria, on police stations, and on government facilities around the protectorate. The revolt began to break down within hours, having failed to achieve key objectives such as the capture of Brunei town and Sultan Omar Ali Saifuddien III. The revolt influenced the Sultan's 1963 decision not to join Malaysia. It is seen as one of the first stages of the Indonesia–Malaysia confrontation.
WThe Communist insurgency in Malaysia, also known as the Second Malayan Emergency, was an armed conflict which occurred in Malaysia from 1968 to 1989, between the Malayan Communist Party (MCP) and Malaysian federal security forces.
WThe Communist insurgency in Sarawak occurred in Malaysia from 1962 to 1990, and involved the North Kalimantan Communist Party and the Malaysian Government. It was one of the two Communist insurgencies to challenge the former British colony of Malaysia during the Cold War. As with the earlier Malayan Emergency (1948–1960), the Sarawak Communist insurgents were predominantly ethnic Chinese, who opposed to British rule over Sarawak and later opposed the merger of the state into the newly created Federation of Malaysia. The insurgency was triggered by the 1962 Brunei Revolt, which had been instigated by the left-wing Brunei People's Party in opposition to the proposed formation of Malaysia.
WThe Indonesia–Malaysia confrontation or Borneo confrontation was a violent conflict from 1963–66 that stemmed from Indonesia's opposition to the creation of Malaysia. The creation of Malaysia was the amalgamation of the Federation of Malaya, Singapore and the crown colony/British protectorates of North Borneo and Sarawak in September 1963. Vital precursors to the conflict included Indonesia's policy of confrontation against Netherlands New Guinea from March–August 1962 and the Brunei Revolt in December 1962.
WThe 2013 Lahad Datu standoff was a military conflict that started on 11 February 2013 and fully ended on 24 March 2013. The conflict began when 235 militants, some of whom were armed, arrived by boats in Lahad Datu District, Sabah, Malaysia from Simunul island, Tawi-Tawi, in the southern Philippines. The group, calling themselves the "Royal Security Forces of the Sultanate of Sulu and North Borneo", was sent by Jamalul Kiram III, one of the claimants to the throne of the Sultanate of Sulu.
WThe Cross border attacks in Sabah are a series of cross border terrorism perpetrated by the Moro pirates from Mindanao on Sabah that began even before the British colonial period. Many civilians have died or suffered during these incidents, causing an increase in anti-Filipino sentiment among the native peoples of Sabah, especially after major attacks in 1985, 2000 and 2013. The attacks were more intense during the presidential terms of Diosdado Macapagal and Ferdinand Marcos who supported irredentist claims to include eastern Sabah as part of the Philippines territory. In addition with the recent infiltration and attacks by militants as well the uncontrolled human migration from Mindanao to Sabah that has led to more unease sentiments among the local residents of Sabah, with around 78% prison inmates that were caught in the state due to involvement in criminal activities and lawlessness issues are mainly originated from the southern Philippines.
