The atomic bombings of Hiroshima on August 6, 1945, and Nagasaki on August 9, 1945, by the United States were the first and only uses of nuclear weapons in warfare, resulting in over 150,000 deaths and forcing Japan's surrender in World War II, which ended the Japanese occupation of Malaya and reshaped global politics.

The installation of the British Military Administration (BMA) in Kuala Lumpur on 12 September 1945 marked the end of Japanese occupation in Malaya and the resumption of British colonial authority, initiating post-war reconstruction amid economic challenges and ethnic tensions.

The Parti Kebangsaan Melayu Malaya (PKMM), or Malay Nationalist Party, was founded on 17 October 1945 in Ipoh, Perak, as the first organized Malay political party in post-World War II Malaya, advocating for independence, nationalism, and social justice amid rising anti-colonial sentiments.

The establishment of Angkatan Wanita Sedar (AWAS) in late 1945 marked the formation of the first nationalist women's organization in Malaya, affiliated with the Parti Kebangsaan Melayu Malaya (PKMM), aimed at awakening Malay women to political consciousness and advancing the independence struggle against British colonial rule.
