The Emergency was declared in 1948 after the Malayan Communist Party launched an armed campaign against British colonial rule. Removals began piecemeal: squatters around Sungei Siput in Perak were cleared to an unprepared site at Pantai Remis in October 1948, a government Squatter Committee recommended in early 1949 that squatters who could not be policed be resettled, and states had moved some 18,500 people by March 1950. From mid-1950 the Briggs Plan made this systematic, ordering the resettlement of roughly half a million rural squatters, overwhelmingly ethnic Chinese who farmed the jungle fringe, into purpose-built settlements that were fenced, guarded, subject to curfew and food control, and administered under Emergency Regulations. The stated aim was to deny the insurgency food, intelligence and recruits; the British administration also invested in housing, schooling and land titles in the villages, and after 1952 conditions were upgraded under General Templer. Roughly 410 New Villages existed by 1952 and most remain populated settlements in Malaysia today. The programme is credited by counter-insurgency literature with helping defeat the insurgency and is criticised by Malaysian Chinese community historians as a coerced mass relocation carried out without consent.
British colonial authorities in Malaya, under the Briggs Plan, moved rural Chinese squatter communities into fenced and guarded settlements to cut off support to the Malayan Communist Party
The 1947 census of Malaya counted about 1.88 million Chinese, roughly 38% of the Federation's 4.9 million people. The Briggs Plan targeted the rural squatter population specifically, generally put at 500,000-600,000 people farming on the jungle fringe.
The resettlement itself was not a mass-casualty event: the sources cited here record no death toll attributable to the moves. Deaths in the wider Emergency, numbering in the thousands across insurgents, security forces and civilians, are counted separately and the figures used vary between British, Malaysian and communist accounts.
