Chin Peng in the context of Secretary (title)

The Malayan Emergency also known as the Anti–British National Liberation War (1948–1960) was a guerrilla war fought in Malaya between communist pro-independence fighters of the Malayan National Liberation Army (MNLA) and the military forces of the Federation of Malaya and Commonwealth (British Empire). The communists fought to win independence for Malaya from the British Empire and to establish a communist state, while the Malayan Federation and Commonwealth forces fought to combat communism and protect British economic and colonial interests. The term "Emergency" was used by the British to characterise the conflict in order to avoid referring to it as a war, because London-based insurers would not pay out in instances of civil wars.

The war began on 17 June 1948, after Britain declared a state of emergency in Malaya following attacks on plantations, which had been revenge attacks for the killing of left-wing activists. Leader of the Malayan Communist Party (MCP) Chin Peng and his allies fled into the jungles and formed the MNLA to wage a war for national liberation against British colonial rule. Many MNLA fighters were veterans of the Malayan Peoples' Anti-Japanese Army (MPAJA), a communist guerrilla army previously trained, armed and funded by the British to fight against Japan during World War II. The communists gained support from many civilians, mainly those from the Chinese community. The communists' belief in class consciousness, ethnic equality, and gender equality inspired many women and indigenous people to join both the MNLA and its undercover supply network, the Min Yuen. Additionally, hundreds of former Japanese soldiers joined the MNLA. After establishing a series of jungle bases the MNLA began raiding British colonial police and military installations.

The Malayan National Liberation Army (MNLA) was a Communist guerrilla army that fought for Malayan independence from the British Empire during the Malayan Emergency (1948–1960) and later fought against the Malaysian government in the Communist insurgency in Malaysia (1968–1989). Many MNLA fighters were former members of the Malayan Peoples' Anti-Japanese Army (MPAJA), including its leader Chin Peng.

The group was also referred to as the Malayan Races Liberation Army owing to a mistranslation.

"Public enemy" is a term to denounce a notorious criminal whose activities are seen as extremely damaging to society.

A notable declared public enemy was Al Capone in the 1930s.
